\"\"

\

The system of equations are \"\", \"\" and \"\".

\

Solve the system of equations by elimination method.

\

Step 1:

\

Eliminate one variable by using two pairs of equations.

\

\"\"

\

Subtract the 2nd and 3rd equations to eliminate the one variable.

\

\"\"

\

Step 2:

\

Solve the system of two equations containing \"\" and \"\" to find \"\" value.

\

\"\"

\

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

\

\"\"                               (Cancel common terms)

\

Substitute \"\" into system of equation of \"\" and \"\" find \"\" value.

\

\"\"               (Substitute \"\")

\

\"\"                    (Multiply)

\

\"\"    (Subtract \"\" from each side)

\

\"\"                    (Apply additive inverse property: \"\")

\

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

\

\"\"                                (Cancel common terms)

\

Step 3:

\

Substitute values of \"\" and \"\" into one of the original equation to find \"\" value.

\

\"\"           (Second equation)

\

\"\"      (Substitute \"\" and \"\")

\

\"\"               (Multiply)

\

\"\"                   (Combine like terms)

\

\"\"   (Subtract \"\" from each side)

\

\"\"                              (Apply additive inverse property: \"\")

\

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

\

\"\"                                (Cancel common terms)

\

Therefore, the solution is \"\", \"\" and \"\".

\

\"\"

\

Check solutions for \"\" and \"\" values.

\

\"\"                  (Third equation)

\

\"\"               (Substitute \"\", \"\" and \"\")

\

\"\"                    (Multiply)

\

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

\

The solution of the system is \"\".

\

\"\"

\

The solution of the system is \"\".
