Question 17446
2(x+4)=3x

You would have to apply the distributive property to this problem. 
1.) 2*x= 2x
2.) 2*4= 8
3.) Since x is unknown we can not change anything involving the variable. So your solution would be 2x + 8 = 3x

<BR>
The above method written by Lainey is right for the most part, though it does not arrive at the right conclusion (In other words, step 3 is wrong). We foil out everything first to get 2x+8=3x. Now we can isolate the variable.
<br>
2x+8=3x (subtract 2x from each side)
8=x
<br>
With that we know that x=8, and so you're solution would not be 2x+8=3x, but 8, as we have successfully solved for x.
