Solve the following system using the elimination method:
10x - 6y = -16
5x + 2y = 22

  • math 3 -

    Add three times the second equation to the first to get:
    (10+15)x=-16+66
    25x = 50
    x=2
    Substitute x=2 into the second equation to get:
    5(2)+2y=22
    2y=22-10=12
    y=6

    Now substitute x=2 and y=6 into the first equation to check solution
    10(2)-6(6)=-16 so solution is correct.
