Question

What is the result of adding these two equations?

Answer 1

Answer:

-2x-7y=-4

Step-by-step explanation:

We want to add the two expressions

$\begin{aligned} 5x-9y &= 1 \\ -7x+2y &= -5 \end{aligned}$

First we add the Left Hand Sides and do the same to the Right Hand Sides. This gives us:

(5x-9y)+(-7x+2y)= 1 +( -5)

Open the brackets

5x-9y-7x+2y=1-5

Regroup like terms

5x-7x-9y+2y=-4

-2x-7y=-4

The result of adding the two given expressions is -2x-7y=-4.
