Question

5 times a number is equal
to three times the sum of the
number and 4. What is the number​

Answer 1

Step-by-step explanation:

Let the required number be x.

∴ Five times the number = 5x

Sum of the number and 4 = x + 4

∴ 3 times the sum of the number and four = 3(x + 4) = 3x + 3 × 4 = 3x + 12

Since, five times the number is equal to three times the sum of the number and 4

∴ 5x = 3x + 12

⇒ 5x-3x = 12

⇒ 2x = 12

⇒x = 6

Hence, the required number = 6

Answer 2

Answer:

let the no is x

5x=3(x+4)

5x=3x+12

5x-3x=12

2x=12

x=12/2

x=6
