solve using the substitution method. If the system has no solution or infinite number of solution state this
4x+4y=36
4x+4y=12

4x + 4y = 36
4x 4x
4y = 4x36
/4 /4 /4
y = x9
Now you substitute this equation into the second one.
4x + 4(x9)= 12
Distribute the 4
4x4x = 36
0x = 36
0 is not equal to 36, so that means this has no solution.
