Question

Solve the system by elimination x+3y=5 -x-y=-3

Answer 1

Answer:

x = 2 y= 1

Step-by-step explanation:

Solve the system by elimination by stacking the equations lining up the variables.

x + 3y = 5

-x - y = -3

Next, add each of the like terms.

    x + 3y = 5

+  -x - y = -3

-----------------------

   0x + 2y = 2

            y = 1

Then substitute y = 1 into one of the equations.

x + 3(1) = 5

x + 3 = 5

x = 2
