4x - 10 + 5x = 719x = 81x = 9
9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7
5x+12 = 4x-88 x = -100
x2+4x-9 = 5x+3 x2+4x-5x-9-3 = 0 x2-x-12 = 0 (x+3)(x-4) = 0 x = -3 or x = 4
5x - 18 = 4x + 7Add 18 to each side:5x = 4x + 25Subtract 4x from each side:x = 25
-5x + x + 9 = -4x + 12 -4x + 9 = -4x + 12 9 = 12 This equation has no solution.
It is a mathematical equation, usually written like this: 5x - 7 + 2x = 3x - 2 + 4x
If: 5x = 4x+7 Then: 5x-4x = 7 And: x = 7
5x + 20 = 4x +30 5x - 4x = 30 - 20 x = 10
5x = 4x + 9 x = 9

5x - 4x = 13 - 3 ie x = 10
4x - 10 + 5x = 719x = 81x = 9
If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
9x + 7 = 5x + 35Subtract 5x from each side of the equation:4x + 7 = 35Subtract 7 from each side:4x = 28Divide each side by 4:x = 7
5x+12 = 4x-88 x = -100
