Solve this system of equations using the addition method.

Question

2x + 5y = 0

x - 5y = -15

Answer 1

you set those equations up nicely one on top of the other makes it easier, just draw a pretend line and add the 2 equations

2x + x = 3x

+5y-5y=0 cancels out

0+(-15)= -15

3x = -15 divide 3 by each side

x = -5 plug this back into the equation to get the y value this is one of your answers now you have to find the y value (iam lazy )
