7-67.

For each equation below, solve for $x$ . Show the process you use to check your answer.

$x - \frac { 2 } { 5 } = 1 \frac { 3 } { 5 }$
Hint (a):
Isolate the variable and constants.
Step 1(a):
$x-\frac{2}{5}=1\frac{3}{5}$
$\;\;\;+\frac{2}{5}\;\;\;+\frac{2}{5}$
Step 2(a):
$\textit{x}=\frac{8}{5}+\frac{2}{5}$
Answer (a):
$x = 2$

$5 x = 0$

$x - 14.6 = 2.96$
