Question

5 less than three times a number gives 28 .Find the number

Answer 1

Step-by-step explanation:

Let the number be x

three times a number = 3x

Answer 2

Answer:

X = 11

Step-by-step explanation:

Let the number be x.

3 times that number = 3x.

Then, the equation is

3x - 5 = 28

Using Transposing method,

3x = 28 + 5 ( When a negative number comes to other side it becomes positive, vice versa)

3x= 33

x = 33/3 ( When a number involved in multiplication comes to other side, it becomes division operation, vice versa)

X = 11

Checking:

To check the answer derived, we substitute the value of x to 11.

3 X 11 - 5 = 28

33 - 5 = 28

28 = 28

Therefore, X = 11
