Taylor was asked to solve the system of linear equations 3x - y = 12 and 10x + 5y = -10
by substitution. His solution is shown below.
Taylor's Solution:
Line 1: 10x + 5(-3x + 12)=-10
Line 2:10x - 15x + 60 = -10
Line 3: -5x +60 = -10
Line 4: -5x = -10 - 60
Line 5: -5x = -70
Line 6: x = 14

Which line is wrong? (pls help I’ll mark as brainliest)
