What is the result of adding these two equations? \begin{aligned} 2x+3y &= -5 \\\\ 5x-y &= -12 \end{aligned} 2x+3y 5x−y
EleoNora [17]

Answer:

7x+2y = -17

Step-by-step explanation:

We have the following equations:

2x+3y = -5

5x-y = -12

If we want to add these equations, we just need to add x-terms, y-terms and independent terms.

(2x+5x)+(3y-y) = -5-12

7x+2y = -17

I hope it helps you!
