Question

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

Answer 1

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!
