Hiya. This is called simple algebra.
Question: 2+5x=16
We need to get 5x by itself. So we need to take the 2 and subtract it on that side, as well as on the 16.
+2-2+5x=16-2
The 2's cancel out. We are left with:
5x=16-2
which is:
5x=14
To get rid of the 5. We need to divide it by 5. Reason is, is that it is multiplied to the "x"
5x/5=14/5
5 divided by 5 is 1. So we are left with:
x=14/5
Answer: x=2.8

that is so simple
you want to get x by itself so rmeber what you do to one side you have to do to the other:
2+5x=16
so minus 2 from each side:
2-2+5x= 16-2
5x= 14
divide each side by 5
5x/5 =14/5
x=2.8 = 14/5
I hope that helps good luck!

subtract 2 from both sides- that leaves you with 5x = 14. Then divide both sides by 5.
x = 2.8

How about instead of asking for the answer you ask someone to help you solve it. You will learn nothing if someone is always giving you the answer... you have to learn the process so you can apply it to future problems.
