Answer:
x =-2.1
Step-by-step explanation:
X/2+10=8.95
Subtract 10 from each side
X/2+10-10=8.95 -10
x/2 =-1.05
Multiply each side by 2
x/2*2 =-1.05*2
x =-2.1
So we are given the expression:
÷ 
When we divide fractions, we must flip the second term and change the sign to multiplication:

And then we multiply across:

Then we can break apart all of the like variables for simplification:

When we simplify variables through division, we subtract the exponent of the numerator from the exponent of the denominator. So we then have:



So then we multiply all of these simplified parts together:

So now we know that the simplified form of the initial expression is:
