Question

Please help. The answer is -11/28, but I can't figure out how to get there.
2/3(x-7)=3/4(4x-5)

Answer 1

2/3(x-7)=3/4(4x-5)

I'd be tempted to multiply by 12

8(x-7)=9(4x-5)

Can you proceed from there?

Answer 2

Clever!

Answer 3

I'm not sure .... sorry...

Answer 4

Do you know how to expand the brackets?

Answer 5

No

Answer 6

I get 8x-42=36x-45

Answer 7

\(8\times7=56\)
Now add multiples of x so that there is only x on one side and the constant on the other.

Answer 8

*add or subtract

Answer 9

so it leaves me with 8x=36x-11

Answer 10

then, x= 28x-11

Answer 11

how do i get -11/28 out of that??
