Okay. One number is 4 more than 3 times a smaller number. Sounds like we have two numbers. So let's set x=larger number y=smaller number.
i did x= the smaller 2x+4= the larger
Okay. Then x is the smaller, and 2x+4 is the larger.
Are you learning systems of equations? or just one variable?
we learned system of equations last year
Okay. I'll straight up tell you that while it might be possible to solve this with just x as a variable, it will be much less confusing to do with x and y.
okay so ill use x and y thankss
Alright. Now really the only reason I set x as the larger number is because it turned up first. y as the smaller number cause it turned up second.
We are looking for two equations that relate x and y. can you figure out the first?
mm. Close, but remember that x is the larger number. You should be getting 3y+4=x
wait no 2(3x+4)-3x=32
ohh wait what?
One number is 4 more than three times a smaller number.
We have a number x that is 4 more than 3 times a smaller number.
ok i got that but then whats the second?
and the smaller number is y. so we have x is 4 more than 3 times y. or, x=4+3y in other words 3y+4=x
If twice the larger number is decreaased by three times the smaller number, the result is 32.
Replace the larger number and smaller number to what we have set them to, x and y ;) Tell me what you get...
Yes. Good! Now we set up the system. 3y+4=x 2x-3y=32
i got 10.6 repeting
Can you show your work? that's not the right answer :S
@inkyvoyd 2(3y+4)-3y=32 6y+8-3y=32 3y+8=32 -8 -8 -------------- 3y=32 --- --- 3 3 y=10.66666666666666666666666666
3y+8=32 catch: 3y+8=24
so x is 13:)
No, check again :)
oh i get itt
thankss sooo muchh
yeah sorry, I made a mistake to. y=8 lol
No problem :)
