Match each equation in the left column with its solution in the right column.
Term:
1. 8(x + 5) = 48
2. 5(2x – 3) = 5
3. 4(x – 8) = 4
4. 3(3x + 1) = 30
Definition:
A) x = 1
B) x = 3
C) x = 2
D) x = 9
~Please help and explain if you can. I just can't seem to wrap my head around how to do it.~

Best ResponseYou've already chosen the best response.1Just solve each equation and then match

Best ResponseYou've already chosen the best response.0That's my problem. I can never get the equation right. I always mess up somewhere in the process.

Best ResponseYou've already chosen the best response.1Or substitute each answer instead of x for example: 8(1+5)=48 8+40=48 So x=1 and so on

Best ResponseYou've already chosen the best response.0Okay.. So how does (1+5) become 40? That's the part I don't understand.

Best ResponseYou've already chosen the best response.1Since you have bracket like this: 8(1+5) You multiply the 8 with the numbers in the bracket 8*1=8 and 8*5=40 So since you have the numbers 8 and 40 which are both positive you will get+8+40 which is equal to +48

Best ResponseYou've already chosen the best response.1Consider this rule so it can help you: \[a(b+c)=ab+ac\]

Best ResponseYou've already chosen the best response.1You just the multiply the outside number with the numbers in the bracket Till here did you understand?

Best ResponseYou've already chosen the best response.0Oh. Okay that makes since. Can you help me with second one? Just so I can make sure I've got it?

Best ResponseYou've already chosen the best response.1The equation is: 5(2x – 3) = 5

Best ResponseYou've already chosen the best response.1Ok so try to get rid of the brackets as I showed you before.

Best ResponseYou've already chosen the best response.0Ok. Don't I have to move the X first though?

Best ResponseYou've already chosen the best response.1No Just multiply the outside number with the numbers and variables in the bracket Consider also this rule:\[a(bx+c)=abx+ac\]

Best ResponseYou've already chosen the best response.1And 5 multiply with 3 is equal to 15

Best ResponseYou've already chosen the best response.1So you have 10x15=5 Now try solving it

InsanityxP

Best ResponseYou've already chosen the best response.0OH! So you multiply 5 by 2, x, and negative 3?

Best ResponseYou've already chosen the best response.0And just to make sure. 4(x – 8) = 4 is D and 3(3x + 1) = 30 is B? Correct?

Best ResponseYou've already chosen the best response.1If you have solved any equation, you should replace your answer with the variable and perform the calculations to get it. For example replace the 2 you have got with x and try calculating it and if you get 5 which is the answer:5(2(2)3)=5 then that means that you have solved the equation correctly. Your welcome
