Hey there!
Here's the answer.
2x+3=8 --> Write the problem.
2x=5 --> Subtract 3 on both sides of the equation.
x=5/2 --> Divide 2 on both sides of the equation.
So the answer is x=5/2 or x=2.5.
Hope it helps!

2.5
All you do is subtract the 3 from 8.
It will then be 2x=5
Divide, and you get 2.5

-3 on both sides leaves u w/ 2x=5
then divide both side by 2
so...x=2.5!
