Question

b) Solve 2x -. 1/5 = x + 8/20​

Answer 1

Answer:

2x - 1/5 = x + 8/20

=> 2x - x = 2/5 + 1/5

=> x = 3/5

Answer 2

Step-by-step explanation:

${:}\longrightarrow$

$2x - \frac{1}{5} = x + \frac{8}{20} \\ = > \frac{10x - 1}{5} = \frac{20x + 8}{20} \\ = > 5(20x + 8) = 20(10x - 1) \\ = > 100x + 40 = 200 x- 20 \\ = > 200x - 20 = 100x + 40 \\ = > 200x - 100x = 40 + 20 \\ = > 100x = 60 \\ = > x = \frac{60}{100}$

${:}\longrightarrow$${\underline{\boxed{\bf{x={\frac {1}{6}}}}}}$
