Question

Two men are decorating a room. One has painted 20 m² and the

other only 6 m². They continue painting and manage to paint
another x m'each. If the first man has painted exactly three times
the area painted by the second man, find the value of x.

Answer 1

• 1 m²

Explanation:

The first man painted:

• x + 20

The second man painted:

• x + 6

If the first man painted 3 times more, then:

• x + 20 = 3(x + 6)
• x + 20 = 3x + 18
• 3x - x = 20 - 18
• 2x = 2
• x = 1
