Simplifying f(x + 7) = x + 49 + 2(x + 7) + -1 Reorder the terms: f(7 + x) = x + 49 + 2(x + 7) + -1 (7 * f + x * f) = x + 49 + 2(x + 7) + -1 (7f + fx) = x + 49 + 2(x + 7) + -1 Reorder the terms: 7f + fx = x + 49 + 2(7 + x) + -1 7f + fx = x + 49 + (7 * 2 + x * 2) + -1 7f + fx = x + 49 + (14 + 2x) + -1 Reorder the terms: 7f + fx = 49 + 14 + -1 + x + 2x Combine like terms: 49 + 14 = 63 7f + fx = 63 + -1 + x + 2x Combine like terms: 63 + -1 = 62 7f + fx = 62 + x + 2x Combine like terms: x + 2x = 3x 7f + fx = 62 + 3x Solving 7f + fx = 62 + 3x Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Reorder the terms: -62 + 7f + fx + -3x = 62 + 3x + -62 + -3x Reorder the terms: -62 + 7f + fx + -3x = 62 + -62 + 3x + -3x Combine like terms: 62 + -62 = 0 -62 + 7f + fx + -3x = 0 + 3x + -3x -62 + 7f + fx + -3x = 3x + -3x Combine like terms: 3x + -3x = 0 -62 + 7f + fx + -3x = 0 The solution to this equation could not be determined.
