6 gallons since the gallons of water is divided by too since the initial value added 1/2 so the number of gallons is divided by too and added to the original amount of gallons so i believe your answer will be 6 gallons

3(x+2)=7 X=1/3 Because 3(x+2) would simplify to 3x+6=7 and then its a two-step equation
