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
