Elimination Method:

\

Write the system of equations by using given mater, Let first number is x and second number is y.

\

$\"\"$ Equation (1)

\

Apply division property of equality: Divide each side by 2.

\

$\"\"$ Equation (1)

\

$\"\"$ Equation (2)

\

Rewite the second equation in terms of first equation.

\

$\"\"$ Equation (2) $\"\"$

\

Neither variable has a common coefficient.The coefficient of the x - variables are 1 and 5 and their least common multipe is 5, so multiply equation(1) by 5 that will make the x - coefficient 5.

\

Add the equations to elimante x - variable.

\

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

\

\

$\"\"$ (Divide each side by 25)

\

$\"\"$ (Cancel common terms)

\

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

\

\

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

\

Apply subtraction property of equality: Subtract 12 from each side.

\

$\"\"$ (Apply additive identity property: $\"\"$ )

\

$\"\"$ (Subtract: $\"\"$ ) $\"\"$

\

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