Answer 2

Question:

$4x - \frac{1}{5} = 7$

Answer:

$The \: value \: of \: \boxed{x \: is \: \frac{9}{5}}$

Step-by-step explanation:

$4x - \frac{1}{5} = 7$

L.C.M. is 5

$\frac{20x - 1}{5} = 7$

Multiplying by 5 on both sides

$5 \times (\frac{20x - 1}{5}) = 5 \times (7)$

$20x - 1 = 35$

$20x = 36 ----------->1$

$5x = 9$

$\boxed{x = \frac{9}{5} }$

Verification:

$Substitute \: \boxed{x = \frac{9}{5} } \: in \: eq \: 1$

$20( \frac{9}{5}) = 36$

$36 = 36$

Hence verified.
