-x + y = 5 x - 5y = 2 ---> x= 5y + 2
I have solved the second equation for x. What is the next step if solving this system with substitution?
A. -(5y+2) + y = 5

B. -x + y = 5 + 5y + 2

C. None of the Above

D. -x + 5y + 2 = 5

A. -(5y+2) + y = 5

Step-by-step explanation:

Solving the above Equation given to us in the Question,

-x + y = 5 Equation 1

x - 5y = 2 Equation 2

Step 1

We make x subject of the formula in Equation 2

---> x= 5y + 2

Step 2

This would be to substitute 5y + 2 for x in Equation 1

-x + y = 5 Equation 1

-(5y+2) + y = 5

Hence, Option A is the correct option
