\

The equations are

\

\"\"                          Equation (1)

\

\"\"                          Equation (2)

\

Since the coefficients of the y-terms are same, you can eliminate these terms by subtracting the equations. Subtract the equations to eliminate variable y.

\

Write the equations in column form and subtract the corresponding columns.\"\"             

\

\"\"                                   (Divide each side by 4)

\

\"\"                                        (Cancel common terms) 

\

\"\"                                           (Divide: \"\")\"\"

\

\

\

 

\

Now Substitute 0 for x in either equation to find the value of y.

\

\"\"                        (Replace x by 0)

\

\"\"                                    (Multiplication property of zero: \"\")
