what is x/3 + 1 = 9

Question

what is x/3 + 1 = 9

anonymous · Answer

$$\frac{ x }{ 3 }+ 1 =9$$
$$3(\frac{ x }{ 3 }) + 1 = 3\times9$$
$$x + 1 = 27$$
$$x + 1 -1 = 27 -1$$
x= 26

Yes, first you have to get the x alone, and do to that you must first subtract $1$ on both sides of the equation, since you are adding $1$ in the equation

$\rm \frac{x}{3}~ + ~1 ~= ~9$

$\rm \frac{x}{3}~ + ~1~-~1 ~= ~9~-~1$

$\rm \frac{x}{3}= ~9~-~1$

So what is $9~-~1$?

You do not do what is connected with the variable first, you always do what isn't paired with the variable when it comes to two-step equations

sammixboo · Answer

$9~-~1~=~8$

So now we plug in $8$ where $9~-~1$ was in the equation.

$\rm \frac{x}{3}= ~8\

Now next to make the x alone we must multiply \(3$ on both sides of the equation, since we are dividing in the original equation 

$\rm \frac{x}{3}\times 3= ~8\times 3$

$\rm x~= ~8\times 3$

Oops LaTeX fail

sammixboo · Answer

But all that you need to do is multiply $8\times 3$

Sorry my answer was wrong at the top. The person above is not 100% correct.
There is no rule that states that you can't start with variable first. It does make it easier at times, but if you have a fraction it's easier to get rid of the fraction first.  
$$\frac{ x }{ 3 }+ 1 = 9$$
$$3(\frac{ x }{ 3 }+ 1) = 3\times9$$
$$x + 3 = 27$$
$$x + 3 -3 = 27 -3$$
$$x = 24$$
