5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
4x - 10 + 5x = 719x = 81x = 9
25
5x+12 = 4x-88 x = -100
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
9x+3-25 = 4x-2 5x = 20 x = 4
5x = 4x + 9 x = 9
33
4x + 5 + x = 25 5x + 5 = 25 Subtract 5 from both sides: 5x = 20 Divide both sides by 5: x = 4
5x - 4x = 13 - 3 ie x = 10
4x - 10 + 5x = 719x = 81x = 9
25
5x+12 = 4x-88 x = -100
