Question

Solve the system by elimination

x+3y=5

-x-y=-3

Answer 1

x = 2 y= 1

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
