The solution to the system of equations:

X+3y =1

-2x - y = -2

We can start by solving the second equation for y:

-2x - y = -2

-y = 2x-2

y = -2x+2

Now we can substitute this expression for y into the first equation:

X+3y =1

X+3(-2x+2) =1

X-6x+6 =1

-5x+6 =1

-5x = -5

x = 1

Now we can substitute x = 1 back into either of the original equations to solve for y:

X+3y =1

1+3y =1

3y = 0

y = 0

Therefore, the solution to the system of equations is x = 1 and y = 0.

Complete question:

Solve: X+3y =1 -2x - y = -2

X+3y =1 -2x - y = -2-example-1
