Answer:
1) x=14
2) n=21/8=2.625
Explanation:
1)
So we have the equation:

First, let's remove all the fractions. Multiply both sides by the LCM of 16, 2, and 8, which is 16. So:

Distribute:

Simplify:

Add 8 to both sides:

So, the value of x is 14.
2)
We have:

Again, let's remove the fractions by multiplying both sides by the LCM of 7 and 8, which is 56. So:

Simplify:

Add 56 to both sides:

Divide both sides by 24:

Reduce:

And we're done!
