The system of equations are .
Rewrite the equation 2: in the form of
.
Subtract y from each side.
\Neither variable has a common coefficient.The coefficient of the y - variables are 5 and 1 and their least common multiple is 5, so multiply each equation by the value that will make the y - coefficient 5.
To get two equations that contain opposite terms multiply the second equation by negative 5.
\Write the equations in column form and add the corresponding columns to eliminate y - variable.
\The resultant equation is .
Divide each side by negative 11.
\Cancel common terms.
\.
Substitute the value of in either of the original equations and solve for y.
The second equation: .
Subtract 11 from each side.
\.
The solution is .
