Solve the systems of equations by substitution.<br> 2x+y=-2<br> 3x-y=7
lukranit [14]

Answer:

To solve the system of equations by substitution:

<u>2x+y=-2</u>

<u>3x-y=7</u>

first solve for y:

2x+y=-2

y=-2x-2

Then plug ^^ equation for y in the other equation

3x-(-2x-2)=7

5x+2=7

5x=5

x=1

Then solve for y:

2(1)+y=-2

y=-4

Final answer is x = 1 and y = -4

Hope it helps!
