Question

Help please: 3(x-4)=2x+8+5x+4

Answer 1

So far I got 3x-12

Answer 2

on the left. right side should be
\[7x+12\] by combining like terms

Answer 3

Distribute the 3 into (x-4)
=> 3x-12=2x+8+5x+4
Add up all the x terms and all the non-x terms:
3x-12=7x+12
Add 12 to each side and subtract 7x from each side:
-4x=24
divide by each side by -4:
x=-6

Answer 4

Answer 5

You just have to think of x as an object. You had 5 x's and you added 2 x's so you have 7 x's.
