Question

How to write eighteen less than 4 times a number is five​

Answer 1

4x - 15 = 5

Explanation:

Let that number be " x ".

4 times a number,

4x

Eighteen less than 4 times a number,

4x - 15

Eighteen less than 4 times a number is five,

4x - 15 = 5

Add 15 on both sides,

4x - 15 + 15 = 5 + 15

4x = 20

Divide 4 on both sides,

4x / 4 = 20 / 4

x = 5

The value of x is 5.

But the question asked only for the equation,

( i.e ) 4x - 15 = 5
