Solve esch system by substitution.

Question

3c+2d=2
d=4

Answer 1

I am not sure what "Solve each system" means, but I would assume with the given information that you need to solve for "c", then solve for "d" with the answer to "c". To do that, your equation would look like this....

3c+2(4) = 2
3c+8 = 2
3c = 2-8
3c = -6
c = -6/3
c = -2

THEN

3(-2)+2d = 2
-6+2d = 2
2d = 2+6
2d = 8
d = 8/2
d = 4

I really do hope this helps.
