Answer:
x = 10
Step-by-step explanation:
In the last step, you can see that the fraction has been multiplied by its reciprocal
, making it cancel out. The reciprocal has been multiplied to both sides, so all you need to do is multiply
·
:
6 · 5 = 30
3 · 1 = 3
<u><em>So now you should have the fraction:</em></u>
x =
<u><em>But, you can still simplify the fraction by dividing 30 by 3:</em></u>
x = 10
