Elimination Method:
\The system of equations are
\ Equation (1)
Equation (2)
Neither variable has a common coefficient.The coefficient of the b - variables are 3 and 2 and their least common multipe is 6, so multiply each equation by the value that will make the b - coefficient 6.
\Elimanted by adding equations.
\Write the equations in column form and add the corresponding columns.
\Apply division property of equality: Divide each side by 31.
\ (Cancel common terms).
Now, find the b value by substituting in either equation.
(Equation 2)
(Multiply:
)
Apply addition property of equality: Add 5 to each side.
\Rearrange the terms using commutative property of addition: a + b = b + a.
\ (Apply additive inverse property:
)
(Apply additive identity property:
)
(Add:
)
(Divide each side by 2)
(Cancel common terms)
The system of solution is .
