Alejandro was asked to solve a system of linear equations by using the substitution method. what is the error in his work below? step 1: 4y + x = 15 −9x + 5y = 20 step 2: 4y + x = 15 x = 15 − 4y step 3: 4y + x = 15 4y + (15 − 4y) = 15 4y + 15 − 4y = 15 15 = 15 there are infinitely many solutions to the system of linear equations
