I know how to do b, c, and g. I need help finding the missing parts.
This is not for a test; this is just some warm up problem from school.

anonymous · Answer

b) 3x+12=18
f)3x=6

Is that what you're looking for? Please ask if you need an explanation :)

I need help with finding the missing steps and reasons for a, d, e, f, h, i, and j.

miracrown · Answer

So you need the reasons for c, d, e, g,h, i and j?Let's start with c
a is nothing, a is the starting point

anonymous · Answer

A is just to write the equation.
