Question

Solve the equation Please

Answer 1

X=-3 so 

Reorder the terms: 5(-4 + x) + 3x + -9x = 6 + -1(2x + 5) + 8x (-4 * 5 + x * 5) + 3x + -9x = 6 + -1(2x + 5) + 8x (-20 + 5x) + 3x + -9x = 6 + -1(2x + 5) + 8x

 Combine like terms: 5x + 3x = 8x -20 + 8x + -9x = 6 + -1(2x + 5) + 8x

 Combine like terms: 8x + -9x = -1x -20 + -1x = 6 + -1(2x + 5) + 8x

 Reorder the terms: -20 + -1x = 6 + -1(5 + 2x) + 8x -20 + -1x = 6 + (5 * -1 + 2x * -1) + 8x -20 + -1x = 6 + (-5 + -2x) + 8x

 Combine like terms: 6 + -5 = 1 -20 + -1x = 1 + -2x + 8x

 Combine like terms: -2x + 8x = 6x -20 + -1x = 1 + 6x

 Solving -20 + -1x = 1 + 6x

 Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-6x' to each side of the equation. -20 + -1x + -6x = 1 + 6x + -6x

Combine like terms: -1x + -6x = -7x -20 + -7x = 1 + 6x + -6x

Combine like terms: 6x + -6x = 0 -20 + -7x = 1 + 0 -20 + -7x = 1 Add '20' to each side of the equation. -20 + 20 + -7x = 1 + 20

Combine like terms: -20 + 20 = 0 0 + -7x = 1 + 20 -7x = 1 + 20

 Combine like terms: 1 + 20 = 21 -7x = 21

 Divide each side by '-7'. x = -3
