Simplifying f(x + 3) = 7x + 7 Reorder the terms: f(3 + x) = 7x + 7 (3 * f + x * f) = 7x + 7 (3f + fx) = 7x + 7 Reorder the terms: 3f + fx = 7 + 7x Solving 3f + fx = 7 + 7x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -7 + 3f + fx + -7x = 7 + 7x + -7 + -7x Reorder the terms: -7 + 3f + fx + -7x = 7 + -7 + 7x + -7x Combine like terms: 7 + -7 = 0 -7 + 3f + fx + -7x = 0 + 7x + -7x -7 + 3f + fx + -7x = 7x + -7x Combine like terms: 7x + -7x = 0 -7 + 3f + fx + -7x = 0 The solution to this equation could not be determined.
