\

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 \"\".
