Solve the system of equations by adding or subtracting. 3x + y = 13
2x + y = 8

The solution of the system is (, ).

The solution of the system is (5, -2)

Step-by-step explanation:

I solved by substitution:

y = 13 - 3x

Then, substitute y = 13 - 3x into 2x + y = 8

You will get 13 - x = 8

Evaluate this to get x = 5

After this, substitute x = 5 into y = 13 - 3x

This will result in getting y = -2

x = 5, y = -2
