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
