multiply
where do I begin with this problem?
6x + 18 = 12x + 12
-------------------
There's nothing to multiply.
Subtract 12 from both sides of the =.
6x + 6 = 12x
Subtract 6x from both sides.
6 = 6x
Divide both sides by 6
1 = x

6x+%2B+18+=+12x+%2B+12 Get all the x on one side by subtracting 6x from each side.
6x+%2B+18+-+6x+=+12x+%2B+12+-+6x Simplify
18+=+6x+%2B+12 Remove the 12 by subtracting 12 from each side
18+-+12+=+6x+%2B+12+-+12 Simplify
6+=+6x Find the value of x by dividing each side by 6.
6%2F6+=+6x%2F6 Simplify
1+=+x
Substitute x=1 into the original equation to check
6+x+1+%2B+18+=+12+x+1+%2B+12
6+%2B+18+=+12+%2B+12
24+=+24 It works
