Question

5. If I multiply a number by 3 and then subtract 4, the result is the same as twice the number. Find this number. ​

Answer 1

4 is the number.

Explanation:

Take the missing number as x,

→ (x × 3) - 4 = (x × 2)

→ 3x - 4 = 2x

→ 3x = 2x + 4

→ 3x - 2x = 4

→ [ x = 4 ]

Hence, the number is 4.
