solve by the substitution method:

8m+n=47

m-5n=52

thank you
having trouble completing please show all work so I can learn better

  • algebra -

    from the 2nd ---> m = 52 + 5n

    into the 1st:
    8(52+5n) + n = 47
    for that I got n = -9

    put that back into
    m = 52 + 5n
    = 52 - 45
    = 7

  • algebra -

    3x=52+5y
    2x=-48-7y
