108 miles 3 hours = 36 mph upstream
108 miles 2 hours = 54 mph downstream
bv = boat velocity in still water
cv = current velocity
bv -cv = 36
bv +cv = 54 Adding both equations
2*bv = 90
boat velocity in still water = 45 mph
since bv + cv = 54
then we know the current velocity = 9 mph

It appears i have made a mistake
Let's solve your equation step-by-step.
7−8+x=11+5
Step 1: Simplify both sides of the equation.
7−8+x=11+5
7+−8+x=11+5
(x)+(7+−8)=(11+5)(Combine Like Terms)
x+−1=16
x−1=16
Step 2: Add 1 to both sides.
x−1+1=16+1
x=17
Answer:
x=17
