hello, hopefully i am putting thisin the right forum. i recently took a placement test to go back to school after 20+ years. i hadn't looked at algebra in a long time and had to reteach myself some online to remember. while i did fairly well on the test one question confused me and i can't seem to get it right. hopefully someone here can explain to me how to solve the equation.
the question was:
2/x - c = 2/k
solve for x.
thank you in advance and sorry if this is in the wrong forum. since it was on a placement test i have assumed it is elementary algebra.
