4x - 8 = 5x 1) Add 8 to both sides. 4x - 8 (+ 8) = 5x (+ 8) Becomes 4x = 5x + 8 2) Subtrate 5x from both sides. 4x (- 5x) = 8 Becomes -1x = 8 Reduced to -x = 8 3) Multiply both sides by -1. Becomes x = -8
20x2 - 27x -8 20 * -8 is -160, and -32 and 5 add to -27 20x2 - 32x + 5x - 8 4x(5x-8) + 1(5x-8) (4x + 1)(5x-8)
-4x + 8 = -4 -4x + 8 - 8 = -4 -8 -4x = -12 -4x/-4 = -12/-4 x = 3
5x-8 + 7x 12x-8 12x = 8 x = 8/12 x= 2/3
7x-3=3x+8 7x-3x=8+3 4x=11 x=11/4=2.75
5x + 3 - 4 + 4x = 9x -1
3x-5
5-4x=x-35-4x+4x=x-3+4x (adding 4x on both side)5=5x-35+3=5x-3+3 (adding 3 on both side)8=5xx=8/5
3x-8+5x+39+4x+51 = x(3+5+4) + -8 + 39 + 51 = 12x +82

9x + 8 = 4x + 23Subtract 8 from both sides9x = 4x + 15Subtract 4x from both sides5x = 15Divide both sides by 5x = 3
4x + 5 = 3x + 84x-3x + 5 - 5 = 3x - 3x + 8 -5x = 3
4x - 8 = 5x 1) Add 8 to both sides. 4x - 8 (+ 8) = 5x (+ 8) Becomes 4x = 5x + 8 2) Subtrate 5x from both sides. 4x (- 5x) = 8 Becomes -1x = 8 Reduced to -x = 8 3) Multiply both sides by -1. Becomes x = -8
2x + 3 + 3x = x + 11 5x + 3 = x + 11 4x + 3 = 11 4x = 8 x = (8/4) x = 2
If you mean: 4x-6+5x = 13x-8 then it works out that x = 1/2 or 0.5
3X - 23 + 4X + 6 = 5X + 8combining like terms, 7X - 17 = 5X + 8subtracting 5X and adding 17 to each side, 7X - 5X = 8 + 17Then, 2X = 25X = 12.5
5 - x - 2 = 3 + 4x + 5 3 - x = 4x + 8 3 = 5x + 8 -5 = 5x x = -1 Check it. 5 - (-1) - 2 = 4 3 + (-4) + 5 = 4 It checks.
