Simplifying F(x) = 4 + -1(2x + 7) + x Multiply F * x xF = 4 + -1(2x + 7) + x Reorder the terms: xF = 4 + -1(7 + 2x) + x xF = 4 + (7 * -1 + 2x * -1) + x xF = 4 + (-7 + -2x) + x Combine like terms: 4 + -7 = -3 xF = -3 + -2x + x Combine like terms: -2x + x = -1x xF = -3 + -1x Solving xF = -3 + -1x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add 'x' to each side of the equation. x + xF = -3 + -1x + x Combine like terms: -1x + x = 0 x + xF = -3 + 0 x + xF = -3 Reorder the terms: 3 + x + xF = -3 + 3 Combine like terms: -3 + 3 = 0 3 + x + xF = 0 The solution to this equation could not be determined.
