What is the solution to the system of equations? 2x + y = -3 x - 2y = -4 ( __ , __ )

(-2,1)

Step-by-step explanation:

2x + y = -3  

x - 2y = -4

Multiply the first equation by 2 so we can eliminate y

2(2x + y = -3  )

4x +2y = -6

Add the second equation

4x +2y = -6

x - 2y = -4

5x   = -10

Divide by 5

5x/5 = -10/5

x = -2

We still need to find y

2x + y = -3  

Substitute x in

2(-2) +y = -3

-4 +y = -3

Add 4 to each side

-4+4 +y = -3+4

y = 1

so, converting firstly the mixed fractions to improper fractions and then "adding".
