8x - 4 = -7 + 5x
8x - 5x - 4 = -7 + 5x - 5x subtract 5x from both sides
3x - 4 + 4 = -7 + 4 add 4 to both sides
3x = -3
x = -3/3 = -1

10x+7 = 5x+32 10x-5x = 32-7 5x = 25 x = 5
If: 10x+7 = 5x+22 Then: 10x-5x = 22-7 And: 5x = 15 So: x = 3

3x - 7 = 5x + 133x - 5x = 13 + 7-2x = 20x = -10x=-3
5x + 7 = 4subtract 7 from both sides5x = -3divide both sides by 5x = -3/5
