2. triciaal

multiply each side of the equation by 3 simplify solve for a

5. gabbyalicorn

now we isolate the variables?

hmm let me check back at one thing...

13. triciaal

you want only terms with a on one side and only numbers on the other side of the equation

18. triciaal

add 18 to each side to keep only the a on the right ; maintain the balance

21. gabbyalicorn

So, one solution.

22. triciaal

|dw:1442268293689:dw|

23. gabbyalicorn

ok, I kind of get that part...

24. triciaal

so to review, isolate means to separate when you have an equation keep the balance simplify divide by the coefficient of the variable

25. gabbyalicorn

o-o okay.
