The system of equations are .

Neither variable has a common coefficient.The coefficient  of the x - variables are 0.2 and 1 and their least common multiple is 0.2, so multiply each equation by the value  that will make the x - coefficient 0.2.

To get two equations that contain opposite terms multiply the second equation by negative 0.2.

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

The resultant equation is and solve for y.

Divide each side by .

Cancel common terms.

.

Substitute the value of in either of the original equations and solve for x.

The second equation: .

Add 9 to each side.

.

The solution is .
