solve by the substitution method

2m+n=9
m-6n=50


the solution is (___,___)

  • substitution method -

    1. 2m + n = 9
    m - 6n = 50

    Using Eq.1, solve for n:
    n = 9 - 2m
    Substitute 9 - 2m for n in Eq. 2:
    m -6(9 -2m) = 50
    Solve for m:
    m - 54 + 12m = 50
    m = 8
    Substitute 8 for m in Eq. 1:
    2(8) + n = 9
    n = -7.

    Solution: m = 8, and n = -7.
