Simplifying f(x + 4) = 7x + 8 Reorder the terms: f(4 + x) = 7x + 8 (4 * f + x * f) = 7x + 8 (4f + fx) = 7x + 8 Reorder the terms: 4f + fx = 8 + 7x Solving 4f + fx = 8 + 7x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -8 + 4f + fx + -7x = 8 + 7x + -8 + -7x Reorder the terms: -8 + 4f + fx + -7x = 8 + -8 + 7x + -7x Combine like terms: 8 + -8 = 0 -8 + 4f + fx + -7x = 0 + 7x + -7x -8 + 4f + fx + -7x = 7x + -7x Combine like terms: 7x + -7x = 0 -8 + 4f + fx + -7x = 0 The solution to this equation could not be determined.
