Simplifying F(x) = 4x + -9f(x + 5) Multiply F * x xF = 4x + -9f(x + 5) Reorder the terms: xF = 4x + -9f(5 + x) xF = 4x + (5 * -9f + x * -9f) xF = 4x + (-45f + -9fx) Reorder the terms: xF = -45f + -9fx + 4x Solving xF = -45f + -9fx + 4x Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '9fx' to each side of the equation. 9fx + xF = -45f + -9fx + 9fx + 4x Combine like terms: -9fx + 9fx = 0 9fx + xF = -45f + 0 + 4x 9fx + xF = -45f + 4x Add '-4x' to each side of the equation. 9fx + -4x + xF = -45f + 4x + -4x Combine like terms: 4x + -4x = 0 9fx + -4x + xF = -45f + 0 9fx + -4x + xF = -45f Reorder the terms: 45f + 9fx + -4x + xF = -45f + 45f Combine like terms: -45f + 45f = 0 45f + 9fx + -4x + xF = 0 The solution to this equation could not be determined.
