Answer 1

Explanation:

Answer 2

I think you want me to find x and y. We need to rearrange the equations.

2x+5y= -1

Subtract 5y on both sides.

2x= -5y-1

Divide everything by 2.

x= -2.5y-0.5

Now, we have what equals x. Plug that in.

4(-2.5y-0.5)+ 5y= -13

Distribute.

-10y-2+5y= -13

Combine like terms.

-5y-2= 13

Add 2 to both sides.

-5y= 15

Divide by -5.

y=-3

Now, plug that in for x.

4x+5(-3)= -13

4x-15= -13

Add 15 on both sides.

4x= 2

Divide by 4.

x=0.5

We can check this.

4(0.5)+5(-3)=-13
2-15= -13
-13=-13

(0.5, -3)

I hope this helps!
