Question

What is the result of subtracting the second equation from the first? \begin{aligned} 2x+7y &= -8 \\\\ 2x-5y &= -1 \end{aligned} 2x+7y 2x−5y ​ =−8 =−1 ​

Answer 1

`12y=-7`

Explanation:

We are given that two equations

`2x+7y=-8`

`2x-5y=-1`

We have to find the result when second equation is subtracting from the first equation.

When second is subtracting from first equation then we get

`12y=-7`

Then , the required result is given by

`12y=-7`

Answer:
`12y=-7`
