Question

Solve each equation for m, then find the value of m for each value of n, show your work.

m + 3n = 7; n = -2, 0, 1

Answer 1

In this problem, we just substitute the given n equal to -2, 0 and 1 to th given equation m + 3x = 7 to find m.
m = 7 - 3n 1. m = 7 - 3*-2 = 7 + 6 = 132. m = 7 - 3*0 = 73. m = 7 - 3*1 = 7-3 = 4
