Three times the sum of a number and 4 is 8 less than one-half the number. Write and solve an equation to find the number.

Question

This question is asking me to right and solve an equation with the situation given. 

Answer 1

3(x+4)=(x/2)-8

 

Hey Savannah,

 

For algebra, it's always super helpful to define your variables right way. With this question, we are trying to find a number, or find the value of x. 

 

Let's now break down the problem.

the sum of a number and 4 would be  x+4. So if we multiply that be 3 we get 3(x+4)

one-half the number would be (x/2). 8 less than that is just subtracting 8 from (x/2) or (x/2)-8.

 

Once you do that, you can create the equation 

3(x+4)=(x/2)-8

 

 

Hope this helps!
