Question

can anybody explain to me what is being done here ?

Answer 1

Answer:

So first, they remove the denominator of x times x, because multiplication cancels out division, so then you're left with

3/1 times x = 2193

3/1 just equals three, so you write it down as 3.

3x = 2193

To isolate 3x, you need to divide by 3.

x = 731

Hope this helped :)

Answer 2

Always the ration over like 2:1 will be 2/1
And Than will put 2193 over x because search for the variable that (x) if you don’t understand please write I will explain
