MCQ
x = 5 and y = -2 is the solution of the linear equation.
  • A
    x + 3y = 1
  • B
    2x + y = 9
  • C
    3x + y = 0
  • D
    2x - y = 12
✓

Answer

  1. 2x - y = 12
    Solution:
    x = 5 and y = -2 is the solution of the linear equation 2x - y = 12
    2x - y = 12
    LHS = 2x - y
    2.5 - (-2)
    10 + 2
    12
    RHS = 12
    LHS = RHS
    It means that x = 5 and y = -2 is the solution of the linear equation 2x - y = 12.
