Simplifying F(x) = -1(x + -7) * 2 + -21 Multiply F * x xF = -1(x + -7) * 2 + -21 Reorder the terms: xF = -1(-7 + x) * 2 + -21 Reorder the terms for easier multiplication: xF = -1 * 2(-7 + x) + -21 Multiply -1 * 2 xF = -2(-7 + x) + -21 xF = (-7 * -2 + x * -2) + -21 xF = (14 + -2x) + -21 Reorder the terms: xF = 14 + -21 + -2x Combine like terms: 14 + -21 = -7 xF = -7 + -2x Solving xF = -7 + -2x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '2x' to each side of the equation. 2x + xF = -7 + -2x + 2x Combine like terms: -2x + 2x = 0 2x + xF = -7 + 0 2x + xF = -7 Reorder the terms: 7 + 2x + xF = -7 + 7 Combine like terms: -7 + 7 = 0 7 + 2x + xF = 0 The solution to this equation could not be determined.
