Does anyone know how to do this? if so, can you explain it?

Step-by-step explanation:

You have to solve for the varible which in this case is 2.

1/2n+7=(n+14)/2

multiply both sides by 2

n +14=n+14

subtract 14 from both sides

n=n

this expression is true

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer
