To solve the equation fm = 8a + 1 when fg = 42, we need to substitute the value of a into the equation and solve for fm.
Given:
fm = 8a + 1
fg = 42
Substitute the value of fg into the equation:
fm = 8a + 1
fm = 8(42) + 1
Evaluate the expression:
fm = 336 + 1
fm = 337
Therefore, when a = 42, fm equals 337.
