How do i do this?

-4.5 = -0.15p

imin eighth grade and i dont get it. please help

- 4.5 = - 0.15p

Now multiply by minus on both sides, we get

4.5 = 0.15p

Now

45/10 = 15/100 * p

Now multiply by 10 on both sides, we get

10 * 45/10 = 10 * 15/100 * p

45 = 15/10 * p

Now divide by 15 on both sides, we get

45/15 = 15/15 *10 * p

3 = 1/10 * p

Now multiply by 10 on both sides. we get

30 = p

Hence p = 30
