Which ordered pair is the solution to the system of equations? {x+5y=-15 y=1/5x+1

x+5y=-15

y=1/5x+1

An easy way to do this is by substitution. The second equation is already set to y, so just plug that into the first equation.

x + 5 (1/5x + 1) = - 15

x + x + 5 = - 15

2x + 5 = - 15

2x = - 20

x = - 10

Now that you've got the x, plug that into one of the equations to find y.

(-10) + 5y = - 15

5y = - 5

y = - 1

So the ordered pair is (-10, - 1).
