HELP PLEASE Acellus Solve this system of equations by using the elimination method.

2 Answer

  • Answer:

    • (2, 2)

    Step-by-step explanation:

    Add up the equations, it will eliminate x as variable:

    • 3x + 6y - 3x + 4y = 18 + 2
    • 10y = 20
    • y = 2

    Find the value of x:

    • 3x + 6*2 = 18
    • 3x + 12 = 18
    • 3x = 6
    • x = 2
  • Given : -

    • 3x + 6y = 18 ... (1)
    • -3x + 4y = 2 ... (2)

    To find : -

    • Solution x and y?

    Solution : -

    3x + 6y = 18

    -3x + 4y = 2 +

    10y = 20

    • y = 20/10 = 2

    3x + 6y = 18

    3x + 6(2) = 18

    3x + 12 = 18

    3x = 18 - 12

    3x = 6

    • x = 6/3 = 2

    • (2 , 2)
