Question

x=4/5 (x+10)
apply x ​

Answer 1

$\\ \tt{:}\longrightarrow x = \frac{4}{5} (x + 10) \\ \\ \tt{:}\longrightarrow x = \frac{4(x + 10)}{5} \\ \\ \tt{:}\longrightarrow x = \frac{4x + 40}{5} \\ \\ \tt{:}\longrightarrow 5x = 4x + 40 \\ \\ \tt{:}\longrightarrow 5x - 4x = 40 \\ \\ \tt{:}\longrightarrow (5 - 4)x = 40 \\ \\ \tt{:}\longrightarrow 1x = 40 \\ \\ \tt{:}\longrightarrow x = 40$
