Simplifying f(n) = 7 + 7(n + -1) Multiply f * n fn = 7 + 7(n + -1) Reorder the terms: fn = 7 + 7(-1 + n) fn = 7 + (-1 * 7 + n * 7) fn = 7 + (-7 + 7n) Combine like terms: 7 + -7 = 0 fn = 0 + 7n fn = 7n Solving fn = 7n Solving for variable 'f'. Move all terms containing f to the left, all other terms to the right. Divide each side by 'n'. f = 7 Simplifying f = 7
