Best ResponseYou've already chosen the best response.1\[\Huge{\frac{1}{2}x+2=x+7}\]\[\Huge{\frac{x+2}{2}=\frac{x+7}{1}}\]By cross multiplication we have,\[\Huge{(x+2)=2(x+7)}\]Solve this for \(x\).

Best ResponseYou've already chosen the best response.4I think you are on track. We only now have to do is divide by 1.5 We now have x = (5/1.5) Using calculator divide 5 by 1.5 and prefix the minus sign.

Best ResponseYou've already chosen the best response.4or I should say 3.333 but it needs to be checked out by substituting it in the original problem to be sure we have not erred. To err is human.

Best ResponseYou've already chosen the best response.4The original equation was:  1/2 x + 2 = x + 7 lets call the answer 3 1/3 and substitute it in the original. we would have: 1/2 (3 1/3) +2 = 3 1/3 + 7 (1/2)(10/3) + 2= 3 2/3 10/6 + 2 = 3 2/3 5/3 + 2 = 3 2/3 3 2/3 = 3 2/3 verified!

Best ResponseYou've already chosen the best response.4Did following that help, just remember the golden rule and you won't unbalance the equation. When you unbalance the equation it will result in an incorrect answer.
