Answer 2

Question:-

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

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

2x - 5y = -1​ -----------(2)

Formula Used- Elimination Method

Answer:-

→ 2x - 5y = -1​ - ( 2x + 7y = -8 )

→  -2x - 7y = +8

   +2x - 5y = -1​

→ 0x -12y = 7

→ y = $\frac{7}{12}$

→ From Equation (1)

2x + 7 × $\frac{7}{12}$ = -8

x = $\frac{-145}{24}$

x = 6.0416
