4x - 10 + 5x = 719x = 81x = 9
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
5x+12 = 4x-88 x = -100
5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
4x-7=5x-2 x=-5
5x = 4x + 9 x = 9
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
4x - 10 + 5x = 719x = 81x = 9
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
5x - 9 = 4x 5x - 4x - 9 = 4x - 4x x - 9 = 0 x - 9 + 9 = 0 + 9 x = 9
5x + 3 = 4xSubtract 3 from each side:5x = 4x - 3Subtract 4x from each side:x = -3
5x+12 = 4x-88 x = -100
5x - 4x = 13 - 3 ie x = 10
4x - 3 - 5x + 7 = 6 4x - 5x = 3 - 7 + 6 -1x = 2 x = -2
5x + 14 = 95 - 4x 5x + 4x = 95 - 14 9x = 81 x = 81/9 x = 9
