Negative three times the sum of two times a number and 1 is equal to 5.” write an equation that represents the equation, then solve

So, we need to consider what is being done.

So, lets start with the -3.

-3*

Now, lets see what's next

2 times a number is the same as saying 2x, then add one.

That is equal to five.  

-3(-2x+1)=5

Now,

6x-3 = 5

6x = 8

x= 8/6
