The work of a student to solve a set of equations is shown
Equation A y = 15 - 22
Equation B: 3y = 3 - 42
Step 1: -3y) = -3(15 -22) (Equation A is multiplied by-3.]
3y = 3-4 Equation B]
Step 2: -3y = 15-22 (Equation A in Step 1 is simplified)
3y = 3 - 42 [Equation B]
Step 3: 0= 18-62 Equations in Step 2 are added]
Step 4: 62 = 18
Step 5: Z=3
In which step did the student first make an error?
Step 4
Step 3
Step 2
Step 1
