4n-6m=-2; n=-2,0,2

Question

solve each equation for m. Then find the value of m for each value of n

Answer 1

4n-6m=-2; n=-2,0,2

First find m:

4n-6m =-2

-6m=-2-4n=-2(1+2n)

3m=1+2n

m=(1+2n)/3

then substitue each value of n to get the 3 values of m

fir the first wherein n=-2

m=[1+{2(-2)}]/3= (1-4)/3=-3/3=-1

do the same with the other 2 values of n.

Answer 2

Given 4n-6m=-2
n=-2,0,2
4(-2)-6m=-2
-8-6m=-2
-6m=-2+8
-6m=6
m=-1

4(0)-6m=-2
-6m=-2
m=1/3

4n-6m=-2
8-6m=-2
-6m=-10
m=10/6
m=5/3
