You must first change the < sign to an equal sign so you can solve the problem
jakyfraze
  • jakyfraze
@breanna1999 how? and what do you mean
breanna1999
  • breanna1999
The right side of the problem has your terms that you must combine and the left side a single term all by itself. This problem is asking you to solve it so you will have 38<4x+3+7-3x becomes 38=4x+3+7-3x
jakyfraze
  • jakyfraze
@breanna1999 ohh okay, so after that whats next?
breanna1999
  • breanna1999
Combine your like terms on the right side
jakyfraze
  • jakyfraze
@breanna1999 starting with 4x + -3x ?
breanna1999
  • breanna1999
Yes and 4x+(-3x)=what's
jakyfraze
  • jakyfraze
1x ?
breanna1999
  • breanna1999
Yes or you could just say x. Now to the next one
jakyfraze
  • jakyfraze
why just say x when it's x1 ?
breanna1999
  • breanna1999
1x is equal to x because there is an imaginary 1 in front of the x
jakyfraze
  • jakyfraze
how?
jakyfraze
  • jakyfraze
if it was 2x 3x 4x 5x 6x it will still equal x?
breanna1999
  • breanna1999
You can just write it as 1x If it helps you
jakyfraze
  • jakyfraze
I'm just wondering
breanna1999
  • breanna1999
My teacher always taught me that if you have 1x you can just leave it as x because of the understood 1 in front of it
jakyfraze
  • jakyfraze
so even if it was 2x and up ? it will still be as x. or is it just the number 1x = x
breanna1999
  • breanna1999
No it's only if you see 1x
jakyfraze
  • jakyfraze
so your saying if it was 2x it will equal 2x, right?
jakyfraze
  • jakyfraze
sorry if I'm confusing you, I'm just confuse my self :(
breanna1999
  • breanna1999
Yes 2x=2x and 3x=3x and so on
jakyfraze
  • jakyfraze
ohh okay thank i was confuse for a minute. so whats the difference between the first question i ask and this one?
jakyfraze
  • jakyfraze
Simplify this expression: 4p + 9 + (–7p) + 2 = ? A. 3p + 7 B. –3p + 11 C. 3p + 11 D. 11p + 11
breanna1999
  • breanna1999
This one involes you needing to solve it
jakyfraze
  • jakyfraze
Solve the following inequality: 38 < 4x + 3 + 7 – 3x. A. x < 28 B. x > 28 C. x < 4 D. x > 4
breanna1999
  • breanna1999
So go ahead and combine your like terms on this equation
jakyfraze
  • jakyfraze
ohh so the first question i did not solve it?
jakyfraze
  • jakyfraze
but this one i have to solve it?
breanna1999
  • breanna1999
You solved by combining like terms for the first one for the second one you have a two step equation
breanna1999
  • breanna1999
So far we have 38=1x+3+7
jakyfraze
  • jakyfraze
38=x 10?
breanna1999
  • breanna1999
38=x+10 is correct now we have to solve the equation. Do you know how to do this?
jakyfraze
  • jakyfraze
im not really sure, can you show me please?
breanna1999
  • breanna1999
Yes I can 38=x+10 38-10=x+10-10 28=x 28
jakyfraze
  • jakyfraze
i dont understand the second step. how did you do that or get that? I'm sorry :(
breanna1999
  • breanna1999
This question is askin you to solve to find the inequality. You must have x on one side by itself. In order to do this you must subtract 10 from both sides
jakyfraze
  • jakyfraze
so subtract 10 from 38 and 10?
breanna1999
  • breanna1999
Yes 10-10 equals 0 and 38-10 equals 28
jakyfraze
  • jakyfraze
ohh, wow. were did you learn this? i want to learn more of this
breanna1999
  • breanna1999
I learned it in algebra 1. There's a website called Khan Academy that can go into further detail
jakyfraze
  • jakyfraze
@breanna1999 is it free?
breanna1999
  • breanna1999
It is
jakyfraze
  • jakyfraze
okay thank you
jakyfraze
  • jakyfraze
so the answer is B. right?
breanna1999
  • breanna1999
Yes
jakyfraze
  • jakyfraze
yessss! thank you
