Please explain how you got your answer, I don't quite understand how to do this.

Question :-

Solve for y in the two equations below using substitution.

2x - 8y = 6 -2x + 2y = 7____________________Solution :-Given Information :-Equation 1 ➢ 2x - 8y = 6 Equation 2 ➢ -2x + 2y = 7 To Find :-Solve for y in the two equations.Calculation :-

Equation 1 ➢ 2x - 8y = 6

Equation 2 ➢ -2x + 2y = 7

Adding both equations together, by combining similar terms, We get,

2x + -2x = 0-8y + 2y = -6y6 + 7 = 13

When we combine the terms, We get,

⇒ -6y = 13

Now, solving for y, by divide Right Hand Side & Left Hand Side by -6, We get,

⇒ y =

⇒ y =

∴ The value of y is

____________________Final Answer :-

The value of y is

Hence, Option C. is correct answer.
