\frac{7}{5}x+3.4=5\times 2+1
Multiply both sides of the equation by 2.
\frac{7}{5}x+3.4=10+1
Multiply 5 and 2 to get 10.
\frac{7}{5}x+3.4=11
Add 10 and 1 to get 11.
\frac{7}{5}x=11-3.4
Subtract 3.4 from both sides.
\frac{7}{5}x=7.6
Subtract 3.4 from 11 to get 7.6.
x=7.6\times \frac{5}{7}
Multiply both sides by \frac{5}{7}, the reciprocal of \frac{7}{5}.
x=\frac{38}{5}\times \frac{5}{7}
