5x + 7 = 3x - 5

First, subtract 3x from both sides.
5x = 7 - 3x = -5
Second, keep the 7 and subtract the 5x - 3x to get 2x.
2x + 7 = -5
Third, subtract the 7 from both sides.
2x = -5 - 7
Fourth, simplify -5 - 7.
2x = -12
Fifth, take the 2 and divide it on both sides, leaving just x in its place.
x =  -\frac{12}{2}
Sixth, since 6 goes into 2 to get 12, simplify the fraction to 6.
x = -6

Answer: x = -6
