\

Elimination Method:

\

The system of equations are

\

$\"\"$ Equation (1)

\

$\"\"$ Equation (2)

\

Neither variable has a common coefficient.The coefficient of the b - variables are 3.29 and 6.28, To make the y - coefficient same multiply equation(1) by 6.28 and equation(2) by 3.29. $\"\"$

\

Add the equations to elimante b - variable.

\

Write the equations in column form and add the corresponding columns.

\

$\"\"$

\

Apply division property of equality: Divide each side by negative 72.7118.

\

$\"\"$

\

$\"\"$ (Cancel common terms)

\

$\"\"$

\

Now, find the y value by substituting $\"\"$ in $\"\"$ .

\

$\"\"$

\

$\"\"$ (Multiply: $\"\"$ ) $\"\"$

\

Apply addition property of equality: Add 22.407 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 3.29)

\

$\"\"$ (Cancel common terms)

\

$\"\"$

\

The system of solution is $\"\"$ .
