(9x + 5 ) - (6x +-8)β
Question
Answer:
Answer: Β x = -4.333333333Step-by-step explanation:Simplifying(9x + 5) + -1(6x + -8) = 0Reorder the terms:(5 + 9x) + -1(6x + -8) = 0Remove parenthesis around (5 + 9x)5 + 9x + -1(6x + -8) = 0Reorder the terms:5 + 9x + -1(-8 + 6x) = 05 + 9x + (-8 * -1 + 6x * -1) = 05 + 9x + (8 + -6x) = 0Reorder the terms:5 + 8 + 9x + -6x = 0Combine like terms: 5 + 8 = 1313 + 9x + -6x = 0Combine like terms: 9x + -6x = 3x13 + 3x = 0Solving13 + 3x = 0Solving for variable 'x'.Move all terms containing x to the left, all other terms to the right.Add '-13' to each side of the equation.13 + -13 + 3x = 0 + -13Combine like terms: 13 + -13 = 00 + 3x = 0 + -133x = 0 + -13Combine like terms: 0 + -13 = -133x = -13Divide each side by '3'.x = -4.333333333Simplifyingx = -4.333333333
