x+?

wut iz 3x+4=2x+7

Last question I answer with wut iz.

Subtract 2x from both sides.

3x-2x+4=2x-2x+7

combine terms.

x+4=7

subtract 4 from both sides.

x+4-4=7-4

combine terms

x=3

The idea here is to get the unknowns on one side (in this exammple the unknown is x) and everything else on the other side. All we have done is moved the xs to one side and the numbers to another and combined terms.
