Nine less than the product of 2 and a number equals 7.

Question

Use the variable c for the unknown number 

Answer 1

Good Morning, Deven,

2c - 9 = 7  <--Nine less than the product of 2 and a number equals 7.


Now you can solve for c, right? 

2c - 9 = 7  <----Add nine to both sides of the equation.



2c = 16    <-----Divide both sides of the equation by 2. 

c = 8 

Let's check our work by plugging 8 into the original equation to see if it checks out, okay? 

Original equation: 

2c -9 = 7

2(8) - 9 = 7 
16 - 9 = 7  
7 = 7 

The solution checks out. I hope I have assisted you and if you have any feedback, please leave your comments under this solution in the comment section. If you need further assistance, you can reach out to any tutor. Have a great day!
