The equations of linear system are .
Rewrite the equation 2: in the form of
.
Subtract 2x from each side.
\.
Since the coefficient of the x - terms in two equations, are additive inverses. So, eliminate these terms by adding the equations.
Write the equations in column form and add to eliminate variable x.
\.
The resultant equation is and solve it for y.
Divide each side by 4.
\Cancel common terms.
\.
Substitute the value of in equation 1:
and solve for x.
Subtract 4 from each side.
\Divide each side by 2.
\Cancel common terms.
\.
The solution is .
The option B is correct answer.
