Astudent is solving the system of equations below. in which line is a mistake first made?
2x + y - 2z = 23
3x + 2y + z = 11
x - y + z = -2
line 1 z = 11 + 3x + 2y
line 2 2x + y - 2(11 + 3x + 2y) = 23
line 3 -4x - 3y = 45
line 4 x - y + (11 + 3x + 2y) = - 2
line 5 4x + y = - 13
line 6 -2y = 32
line 7 y = 16, x = ¾, z = -11/4
