Elimination Method:
\The system of equations are
\ Equation (1)
Equation (2)
Neither variable has a common coefficient.The coefficient of the y - variables are 1 and 4 and their least common multipe is 4, so multiply equation(1) by 4 that will make the y - coefficient 4.
\Subtract the equations to elimante y - variable.
\Write the equations in column form and subtract the corresponding columns.
\Apply division property of equality: Divide each side by 35.
\ (Cancel common terms).
Now, find the y value by substituting in either equation.
(Equation 1)
(Multiply:
)
Apply subtraction property of equality: Subtract 24 from each side.
\Rearrange the terms using commutative property of addition: a + b = b + a.
\ (Apply additive inverse property:
)
(Apply additive identity property:
)
(Subtract:
)
The system of solution is .
