The system of equations are
.
Neither variable has a common coefficient.The coefficient of the x - variables are 4.9 and 0.7 and their least common multiple is 4.9, so multiply each equation by the value that will make the x - coefficient 4.9.
\To get two equations that contain opposite terms multiply the second equation by negative 7.
\\
\
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 first equation:
.


Add 2.4 to each side.
\

Divide each side by 4.9.
\
Cancel common terms.
\\
.
The solution is
.
