Answer:

The number  x = 3

Step-by-step explanation:

Explanation

Let 'x' be a number

Given that  multiply it by 5 and then add 7 The answer is 22

5 x + 7 = 22

subtracting '7' on both sides, we get

5 x + 7 - 7 = 22 -7

5 x  = 15

Dividing by '5' on both sides, we get

[tex]\frac{5x}{5} = \frac{15}{5}[/tex]

x = 3

The number  x = 3
