Answer:
The result of subtracting the second equation from the first
We Get,
[tex]y=\frac{-7}{12}[/tex]
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 )
∴ [tex]2x + 7y -2x+5y=-8+1\\\\2x-2x+7y+5y=-7\\0 +12y=-7\\\\y=\frac{-7}{12}[/tex]
We Get,
[tex]y=\frac{-7}{12}[/tex]
