Question

Solve using the substitution method. Show your work. If the system has no solution or an infinite number of solutions, state this.

4x+4y=-36
4x+4y=12

Answer 1

no solution

Answer 2

subtracting the two equations give you 0=-48 which is not true

Answer 3

Is it because they are both +4y and 4x, I didnt think so either. Because there is no - on the bottom half.

Answer 4

so no solution

Answer 5

no work necessary.
if a=b and b=c then a=c
so
4x+4y=-36
and
4x+4y=12
then
-36=12 which it doesnt
