Answer 2

like this?

Answer 3

Yes thats right :) I must solve

Answer 9

@robtobey Hello! How do you achieve the -7?

Answer 10

Multiply each side of the equation by 20, "4 times 5".\[\frac{20}{5} (2 (x+12))=20 \left(6-\frac{9-x}{4}\right) \]\[8 x+96=5 x+75 \]Can you complete the solution from here?

Answer 11

Some of the terms may not appear exactly as those written in the original problem statement, but they are still valid.

Answer 12

\[3 x=75-96 \]\[3 x=-21 \] x = -7
