The work of a student to solve a set of equations is shown:
equation a: y = 15 β 2z
equation b: 2y = 3 β 4z
step 1: β2(y) = β2(15 β 2z) [equation a is multiplied by β2.]
2y = 3 β 4z [equation b]
step 2: β2y = 15 β 2z [equation a in step 1 is simplified.]
2y = 3 β 4z [equation b]
step 3: 0 = 18 β 6z [equations in step 2 are added.]
step 4: 6z = 18
step 5: z = 3
in which step did the student first make an error?
a: step1
b: step 2
c: step 3
d: step 4
