The equations are
\Since the coefficients of the y-terms, +1 and +1, 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)
Now Substitute for x in either equation to find the value of y.
(Equation 1)
(Zero propduct property:
)
(Apply additive identity property:
)
The solution is .
The solution is .
