The system of equations are $\"\"$ .

Neither variable has a common coefficient.The coefficient of the y - variables are 0.1 and 1 and their least common multiple is 0.1, so multiply each equation by the value that will make the y - coefficient 0.1.

To get two equations that contain opposite terms multiply the second equation by negative 0.1.

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

$\"\"$

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

Divide each side by 0.4.

$\"\"$

Cancel common terms.

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

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

The second equation: $\"\"$ .

$\"\"$

Subtract 1 from each side.

$\"\"$

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

The solution is $\"\"$ .
