Solve/isolate "x" ... 2x+7
First: combine "like" terms --- subtract 7 from both sides (when you move a term to the opposite side, always use the opposite sign)....
2x + 7 - 7
2x
2x
Sec: isolate the "x" variable on one side --- divide both terms by "2"....
2x/2
x
x

you first ought to get X via itself. to try this subtract the three away. So now you have 2X=-2 The to get the X thoroughly via itself you divide the two away (considering the fact that's the guideline, to divide). So X =-one million (and it relatively is considering you divided the two far flung from the X and on the different area it grow to be divided via the -2. desire that enables.
