Welcome back and happy Monday! I hope everyone's weekend was fun and will talk about mine later on Free-Write Friday. Today we are going to "discuss" how to solve the equation "2x-7=15." Here, we go...

#1 Figure and Define.

2,7, and 15 are all digits

- means we are going to subtract

"x" is just a variable. It could be any imaginable number.

#2 Solve (Now that we know what everything is)

2x-7=15

YOU HAVE TO GET THE VARIABLE (x) ALONE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

So, subtract 2 from each side. 2-2=0 and 15-2=13

Now we have x-7=13

#3 Finish it off

Since 7 is -7 in this case, we will add to get zero (negative plus positive is zero if its the same number)

-7+7=0 and 13+7=20

Now we have x=20

#4 Double-Checker

Double check your work and make sure all your numbers are correct.

I've double checked my work and i know it to be true.

x=20

Horray!!!!!!!!!!!!!!!!!!!
