The equations of linear system are .
Since the coefficient of the y - term in two equations is same. So, eliminate these terms by subtracting the equations.
Write the equations in column form and subtract to eliminate variable y.
.
The resultant equation is and solve it for x.
Divide each side by 4.
Cancel common terms.
.
Substitute the value of in equation 1: and solve for y.
Subtract 3 from each side.
.
The solution is .
