The system of equations are
.
Neither variable has a common coefficient.The coefficient of the x - variables are 1 and 5 and their least common multiple is 5, so multiply each equation by the value that will make the x - coefficient 5.
\To get two equations that contain opposite terms multiply the first equation by negative 5.
\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 negative 9.
\
Cancel common terms.
\
.
Substitute the value of
in either of the original equations and solve for y.
The equation 1:
.


Add 3 to each side.
\
.
The solution is
