The linear system is
Rewrite the equations in the form of ,
and
.
Draw a coordinate plane
\Draw the linear equation
Draw the linear equation
Plot the intersection point
Check:
\To check solution, substitute x for and y for 0 in the linear equations.
(Substitute x for
and y for 0)
(Product of two same signs is positive) \ \
(Multiply:
) \ \
(Apply additive inverse property:
)
(Substitute x for
and y for 0)
(Apply additive inverse property:
)
The point satisfies the linear system. so, the solution is
The solution is .
