Make x the subject of the equation. 7xy+6 = 18x+3y+7

Put all the terms which contain x onto one side of the equation.-6 from both sides of the equation and -18x from both sides of the equation to get7xy-18x = 3y+7-6Simplify if possible7xy-18x = 3y+1Take the x outside the brackets to get it by itselfx(7y-18)=3y+1Divide both sides by the brackets to get your answerx=(3y+1)/(7y-18)
