The equation that models the verbal description is [tex]\frac{x + 5}{3}[/tex] = 7.
The number described is 16
Let x represent the number described
The following equations model the given verbal description :
- A number is increased by 5 : x + 5
- the result is divided by 3 : [tex]\frac{x + 5}{3}[/tex]
- the result is 7 : [tex]\frac{x + 5}{3}[/tex] = 7
In order to determine the value of x, take the following steps
- multiply both sides of the above equation by 3
x + 5 = (7 x 3)
x + 5 = 21
- Subtract 5 from both sides of the equation
x = 21 - 5
x = 16
