Eight less than 7 times a number is the same as 4 more than 3 times the number.

7x-8 = 3x+4

Step-by-step explanation: In this case, I'm purposely going to solve for "x".

First you eliminate 3x by subtracting 3x  and it looks like this: 3x

                                                                                                          -3x                                        

Leaving the equation like this 4x-8=4

Then you eliminate 8 by adding 8 and doing the same thing to the other side

Lastly the equation is going to look like this: 4x=12

Then you divide leaving x=3

The answer is x=3                    

b and c

step-by-step explanation:

answer: 0

step-by-step explanation: the positive, like 5, + its opposite, like -5 would be 0

5+(-5)=0, or 5-5=0
