Solving systems of equations using substitution

y=-5

5x+4y=-20


please help m figure out how to do these types of problems I seriously don't get it

You are told that y=-5, so just use that value for y in the second equation...

5x+4(-5)=-20

5x-20=-20

5x=0

x=0 so the solution, when the lines intersect, is the point (0,-5)
