\

The system of equations are $\"\"$ and its solution is $\"\"$ .

\

Substitute the values of $\"\"$ in the above linear system.

\

Equation 1: $\"\"$ .

\

Equation 2: $\"\"$ .

\

Neither variable has a common coefficient.The coefficient of the a - variables are 2 and 1 and their least common multiple is 2, so multiply each equation by the value that will make the a - coefficient 2.

\

To get two equations that contain opposite terms multiply the second equation by 2.

\

\

Write the equations in column form and add the corresponding columns to eliminate a - variable.

\

$\"\"$ . $\"\"$

\

The resultant equation is $\"\"$ and solve for b.

\

Divide each side by 3.

\

$\"\"$

\

Cancel common terms.

\

$\"\"$ .

\

Substitute the value of $\"\"$ in either of the original equations and solve for a.

\

The second equation: $\"\"$ .
