Explanation:

Greetings !

From, the given word explanation try to create your own equation like

• x + y = 36... (1) let the two numbers be x and y respectively.
• 2x = y ....(2) let x be the first no and it's twice that of the second number.

From, equation (1) solve for x

• x + y = 36
• x = 36-y... (3)

Substitute, equation (3) to equation (2).

• 2(36-y) =y
• 72 - 2y =y
• 72 = y + 2y.... solve for y
• 72 = 3y.... divide both sides by 3
• 72/3 = y..
• y=24 ...simplified
