Question

Solve each system of equations of equations.

x + y = -6

2x - y = 3​

Answer 1

x = -1, y = -5

Explanation:

x + y = -6

2x - y = 3​

Add the two equations together to eliminate y

x + y = -6

2x - y = 3​

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

3x = -3

Divide by 3

3x/3 = -3/3

x = -1

Now find y

x+y = -6

-1+y = -6

Add 1 to each side

-1+1 +y = -6+1

y = -5
