The system of equations are
.
Neither variable has a common coefficient.The coefficient of the x - variables are
and their least common multiple is
, so multiply each equation by the value that will make the x - coefficient 0.5.
To get two equations that contain opposite terms multiply the first equation by negative 0.5.
\\
\
\
Write the equations in column form and add the corresponding columns to eliminate x - variable.
\
The resultant equation is
and solve for y.
Multiply each side by negative 1.
\

Substitute the value of
in either of the original equations and solve for x.
The first equation:
.


Add 2 to each side.
\
.
The solution is
.
