You Must Solve For The Value Of X To Make The Equation True. 
So, There Are Two Ways We Could Try This:
Guess And Check
Or
Solve
I Am Going To Show You How To Solve This Because That Is What You Need To Know. So, We First Need To Look At It.
6x + 3 = 2x + 8
So, we need to subtract 3 from the right side's 8 to begin.
The equation becomes:
6x = 2x + 5
Now, We Need To Simplify The 2x. Subtract 2x from 6x. 
The Equation Becomes:
4x = 5
Now, Divide.
4x/4 = 1x = X
So, 
X = 5/4
5/4 = 1 and 1/4
So
X = 1 ¼
