Given the equation:
5/2 = 2/x
Solve for x.
Solution:
In order to solve for x, we simply need to multiply first x on both sides of the equation, this cancels out 2/x on the denominator.
5/2 = 2/x
(x) 5/2 = (x) 2/x
5/2x = 2
Now we need to multiply both sides by 2/5 which is the reciprocal of 5/2 in order to cancel out 5/2x, leaving behind x.
(2/5)(5/2x) = 2 (2/5)
x = 4/5
Final answer:
x = 4/5
