Step-by-step explanation:
It all depends on the math question but usually you solve for x, then check it. Plug x back in and see if it works. But it all depends on the math problem
If <em>x</em> = 4.338338338…, then
1000<em>x</em> = 4338.338338338…
and subtracting <em>x</em> from this eliminate the trailing decimal.
1000<em>x</em> - <em>x</em> = 4338.338338338… - 4.338338338…
999<em>x</em> = 4334
<em>x</em> = 4334/999
