4x - 10 + 5x = 719x = 81x = 9
5x+12 = 4x-88 x = -100
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
8x + 5x + 2x + 4x = 114 19x = 114 x = 6 then 5x + 3 = 5*6 + 3 = 33
5x = 4x + 9 x = 9
33
5x - 4x = 13 - 3 ie x = 10
4x - 10 + 5x = 719x = 81x = 9
5x+12 = 4x-88 x = -100

4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
