The equations of linear system are
.
Rewrite the equation 1:
so that the like terms are arranged in column.
Add 4.8x to each side.
\

Subtract 1.7y from each side.
\\

.
Since the coefficient of the y - terms in the above two equations
are additive inverse, eliminate these terms by adding the equations.
Write the equations in column form and add to eliminate variable y.
\
.
The resultant equation is
and solve it for x.
Divide each side by negative 8.4.
\
Cancel common terms.
\
.
Substitute the value of
in equation 2:
and solve for y.

Subtract 12.8 from each side.
\

Divide each side by 1.7.
\
Cancel common terms.
\
.
The solution is
.
