What is the result of subtracting the second equation from the first?
2x+7y
2x−5y


=−8
=−1

The result of subtracting the second equation from the first

We Get,

Step-by-step explanation:

Given:

2x+7y = -8    .................Equation( 1 )

2x−5y  = -1    .................Equation( 2 )

To Find:

What is the result of subtracting the second equation from the first

i.e Equation( 1 ) - Equation( 2 ) = ?

Solution:

Subtracting the second equation from the first means

Equation( 1 ) - Equation( 2 )

( 2x + 7y ) - ( 2x−5y  ) = -8 - ( -1 )

∴

We Get,

5   1/4   miles per hour

step-by-step explanation:

15   3/4 / 3 = 5   1/4
