M + 2n = 14 Rearrange M = 14 - 2n Now take that m value and susbsitute it for the m value in the other equation 2(14 - 2n) - n = 13 28 - 4n - n = 13 Combine like terms 28 - 5n = 13 Solve for n -5n = - 15 n = 3 Now put this n value back into one of the original equations to solve for m M = 14 - 2(3) M = 8
