Elimination Method:
\The system of equations are
\ Equation (1)
Equation (2)
Neither variable has a common coefficient.The coefficient of the y - variables are 4.6 and 2.8, To make the y - coefficient same multiply equation(1) by 2.8 and equation(2) by 4.6.
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 33.82.
\ (Cancel common terms)
Now, find the y value by substituting in
.
(Multiply:
)
Apply addition property of equality: Add 15.91 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 negative 4.6)
(Cancel common terms)
The system of solution is .
