Question

Properties of Equaliity, How do I start this off?
6 = -10 - p/5

Answer 1

u trying to solve it for p value ?

Answer 2

Yes.

Answer 3

so.. we need to do something and isolate p

Answer 4

I wanna say multiplication...?

Answer 5

wow.. u r right
lets multiply both sides with 5

Answer 6

Okay I got 30 = -50 - p/5? Is that right?

Answer 7

\[5 * 6 = 5(-10) - 5*\frac{p}{5}\]

Answer 8

\[30 = -50 - p \]

Answer 9

our goal is to isolate p..
we need to get rid of 50... what can we do now ?

Answer 10

Add like terms?

Answer 11

yep... by adding which "-50" gets cancelled ?

Answer 12

i meant, by adding which number..

Answer 13

-50 + 50 is now a 0 so I add -50 to 30?

Answer 14

any number we add, we need to add to both sides. thats the "property of equality"

we cant just add to LHS, and equate it to RHS

Answer 15

think again... which number will cancel out "-50" ?

Answer 16

30 = -50 - p

Answer 17

It's not the 30 but the 5?

Answer 18

if we add "-50" to both sides, RHS becomes "-100 - p" !!!

Answer 19

its the "-50" we want to cancel below :
30 = -50 -p

Answer 20

so.. if we add "50" both sides....

50 + 30 = 50-50-p

Answer 21

its cancelling out right.. on RHS... u see ?

Answer 22

Yup, It's 80 = -p/5 now?

Answer 23

no.. there is no 5 on bottom of "-p"

Answer 24

80 = -p

multiply "-1" both sides
-80 = p

p = 80

Answer 25

Oh okay I get it, thank you for your time!

Answer 26

is it good for you that explanation... or you still uneasy ?

Answer 27

yw.. :)
