Question

The sum of a number and 4.8 is three times the number. Find the number

Answer 1

Answer:

The answer is Z = 2.4

Step-by-step explanation:

Let the number be Z

Z + 4.8 = 3 × Z

Z + 4.8 = 3Z

Collect like terms

4.8 = 3Z - Z

4.8 = 2Z

Z = 4.8/2

Z = 2.4

Answer 2

Answer:

The number is 2.4

Step-by-step explanation:

Let the number be y

The sum of the number and 4.8 is written as: y + 4.8

Three times the number is written as: 3y

From the question, we were told that the sum of the number and 4.8 is three times the number. This is illustrated as:

y + 4.8 = 3y

Collect like terms

4.8 = 3y — y

4.8 = 2y

Divide both side by the coefficient of y i.e 2

y = 4.8/2

y = 2.4

The number is 2.4
