2x+3x = 5x

3x+5 = 2x+13 3x-2x = 13-5 x = 8

3x + 5x = 2x + 28x = 2x + 26x = 2x = (2/6) = 1/3

3x + 2x = 40 5x = 40 x = 8

-3x + 2x = 6Let's abbreviate left part by cancellation:-x = 6The answer will be:x = -6

-2x^4+16 +2x^4+9-3x^5=-3x^5+25. There is no "answer" because there is no equation.

-3x + (-18) = 2x + 7 +18 +18 -3x = 2x +25 -2x -2x -5x = 25 ----- ----- -5 -5 x=-5 *------- equals a division line

3x - 3 = 2x + 6 3x = 2x + 9 x = 9

2x + 2 = 3x - 57 = x

x = 5 ========== 3x - 9 = -2x + 16 Balance the equation by adding 2x and 9 to both sides: 3x + 2x = 16 + 9 5x = 25 Divide both sides by 5 to get value for x: x = 5
