Question

X/2 -5=20 please give details

Answer 1

Answer: x=50

how?

$\frac{x}{2}$ - 5= 20 (first ADD 5 with 20 whatever you do on one side you have to do it to the other) so that gives us:

$\frac{x}{2}$=25 (we see that 2 is being divided by x and we want X alone so the inverse of division is MULTIPLICATION)

25 x 2= 50

therefor the x=50
