What is the result of subtracting 2x-5y=-1 from 2x+7y=-8

The result of subtracting the equation is 12 y + 7 = 0

Step-by-step explanation:

Given equation as :

2 x - 5 y + 1 = 0       and

2 x + 7 y + 8 = 0

Now Subtract the given equation

( 2 x - 5 y + 1 ) - ( 2 x + 7 y + 8 ) = 0

Or, ( 2 x - 2 x ) - ( 5 y + 7 y ) + ( 1 - 8 ) = 0

Or,  ( 0 ) - ( 12 y ) + ( - 7 ) = 0

Or,  12 y = - 7

∴         y = -

Hence The result of subtracting the equation is 12 y + 7 = 0    Answer
