Question

What is the result of subtracting the second equation from the first -2x+7y=10 3x+7y=2

Answer 1

Answer:-5x = 8

Explanation:

-2x + 7y = 1=

-(3x + 7y) -(2)

__x + __y=__

-2x + 7y = 10

-(3x + 7y) 1(2)

-5x = 8

Answer 2

The answer after subtracting the following equation is x= -8/5

Explanation:

• -2x+7y=10 ----- eq(1) , 3x + 7y =2------ eq(2)

• 7y+3x =2

• 7y-2x = 10

• subtracting eq 2 from eq 1 we get

• 5x = -8

• x= -8/5
