Question :

-0.8+0.5x=0.2(x+2)

To Find :

The value of x=?

Answer:

$\\ \large \longrightarrow \bf \: - 0.8 + 0.5x = 0.2(x + 2)$

$\\ \large\longrightarrow \sf \: - 0.8 + 0.5x = 0.2x + 0.4$

$\\ \large\longrightarrow \: \sf- 0.8 + 0.5x - 0.2x - 0.4 = 0$

$\\ \large \longrightarrow \sf \: 0.3x - 1.2 = 0$

$\\ \large \longrightarrow \sf \: 0.3x = 1.2$

$\: \\ \large\longrightarrow \sf x = \frac{1.2}{0.3} = \frac{12}{3} = 4$
