Solve and check each system of equations by substitution method 4x + y = -2
(2x=-y

x=-1 and y=2

Step-by-step explanation:

Given, and

Solution, equation 1

Now substituting the value of y in equation 1, we get;

Now

So the solution of the given equation is x=-1 and y=2

Check:

Substituting the value of x and y in  equation 1 we get;

L.H.S=R.H.S

Substituting the value of x and y in  equation 2 we get;

L.H.S=R.H.S

a is the right answer
