5x+7=7-4x-\left(-4\right)
To find the opposite of 4x-4, find the opposite of each term.
5x+7=7-4x+4
The opposite of -4 is 4.
5x+7=11-4x
Add 7 and 4 to get 11.
5x+7+4x=11
Add 4x to both sides.
9x+7=11
Combine 5x and 4x to get 9x.
9x=11-7
Subtract 7 from both sides.
9x=4
Subtract 7 from 11 to get 4.
x=\frac{4}{9}
Divide both sides by 9.
