The equations are
\ Equation (1)
Equation (2)
Multiply the first equation by 3
\
Equation (3)
Multiply the second equation by 2
\
Equation (4)
Since the coefficients of the y-terms are same y-terms can be eliminated by subtracting the equation 4 from 3.
\Write the equations in column form and subtract the corresponding columns.
\ (Divide each side by negative 32)
(Cancel common terms)
(Divide:
)
Now Substitute for x in either equation to find the value of y.
(Equation 1)
(Multiply:
)
(Add 2 to each side)
(Apply commutative property of addition:
)
(Apply additive inverse property:
)
(Apply additive identity property:
)
(Divide each side by 2)
(Cancel common terms)
The solution is .
