Can someone help me?
What is 8=6+x/2?

8 = 6+x/2

Get rid of the denominator: LCM of all denominators( in this case we only have 1 denominator ) , then multiply to all expressions

8x2 = 6+x/2x2

The denominator 2 gets crossed out as well as the other 2

16 = 6+x

Now constants on one side and variables on the other

16-6 = 6-6+ x

Now your answer

10= x

Or

x = 10
