2x-6y+2=3

5x-2y+5z=9

Simplifying 8x + 336 = 336 + - 3x Reorder the terms: 336 + 8x = 336 + - 3x Add '-336' to each side of the equation. 336 + - 336 + 8x = 336 + - 336 + - 3x Combine like terms: 336 + - 336 = 0 0 + 8x = 336 + - 336 + - 3x 8x = 336 + - 336 + - 3x Combine like terms: 336 + - 336 = 0 8x = 0 + - 3x 8x = - 3x Solving 8x = - 3x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '3x' to each side of the equation. 8x + 3x = - 3x + 3x Combine like terms: 8x + 3x = 11x 11x = - 3x + 3x Combine like terms: - 3x + 3x = 0 11x = 0 Divide each side by '11'. x = 0 Simplifying x = 0
