The linear equation is
.
Fractions with different denominators can not be added. So, write the equation with common denominator.
\Find the least common denominator L.C.M.
\Multiples of 7 = 7, 14, 21, 28, 35, 42, ......
\Multiples of 6 = 6, 12, 18, 24, 30, 36, 42, .........
\Least Common Multiple of 7 and 6 is 42
\Write the left hand side equation with common denominator
\
\

Since denominators are same add the numerators over the denominator
\
Multiply each side by 42.
\
Cancel common terms.
\
Apply distributive properties :
.

Subtract 1596x from each side. \ \
\
Apply Additive Inverse Property: a + (-a) = 0.
\
Group like terms.
\
Combine like terms.
\
Divide each side by negative 1550.
\
Cancel common terms.
\
