Elimination Method:
\The system of equations are
\ Equation (1)
Equation (2)
Neither variable has a common coefficient.The coefficient of the k - variables are 3 and 8 and their least common multipe is 24, so multiply each equation by the value that will make the k - coefficient 24.
\Add the equations to elimante k - variable.
\Write the equations in column form and add the corresponding columns.
\Apply division property of equality: Divide each side by 102.
\ (Cancel common terms).
Now, find the k value by substituting in
.
(Multiply:
)
Apply addition property of equality: Add 48 to each side.
\Rearrange the terms using commutative property of addition: a + b = b + a. \ \
\ (Apply additive inverse property:
)
(Apply additive identity property:
)
(Subtract:
)
(Divide each side by 8)
(Cancel common terms)
The system of solution is .
