Mathematics
1 answer:

Answer: one solution at ( -1, 2 )

Step-by-step explanation:

-x + 2y =5

x + y = 1

You cross out the x’s then add 2y + y which will give you 3y. Add the 5 and 1 and you’ll get 6.

3y = 6

Divide 3 to both sides

y = 2

To get x you’ll use the first equation.

-x + 2y = 5

Replace the y with 2

-x + 2(2) = 5

-x + 4 = 5

Move the 4 to the other side, but you’ll need to flip it to negative. So 5 - 4.

-x = 1

Divide both sides by -1

x = -1
