## anonymous 3 years ago x.5 - 1=9 what does x=?

1. anonymous

is that x * 5? or x + 5 or x - 5 or x/5?

2. anonymous

x/5

3. anonymous

x/5 - 1 = 9 add one to each side x/5 = 10 then multiply each side by 5

4. anonymous

so it would be 50/5?

5. anonymous

$\frac{ x }{ 5 } * \frac{ 5 }{ 1 } = 10 * 5$

6. anonymous

cross cancel on the left side to get what?

7. anonymous

2/5

on the left side since we're multiply we can cross cancel the two 5's for one is the denominator and the other is the numerator. once we cross cancel they become 1 so x/1 also equals x
