Answer:
x = 8
Step-by-step explanation:
3+x/8=4
We move all terms to the left:
3+x/8-(4)=0
We add all the numbers together, and all the variables
x/8-1=0
We multiply all the terms by the denominator
x-1*8=0
We add all the numbers together, and all the variables
x-8=0
We move all terms containing x to the left, all other terms to the right
x=8
