Question

Solve the equation. 15/m - m + 8 = 10

Answer 1

we can say :
15/m-m=10-8
k ?:)

Answer 2

ok!

Answer 3

you have to simplify the equation, and then factorise it at the end to get your answers

Answer 4

15/m-m=10-8
15/m-m^2/m=2
15-m^2/m=2
Factor from m :
m(m-15)/m=2
have :
m-15=2
m=15+2
m=17
Got it ?:)

Answer 5

lol i dont think thats it

Answer 6

Why ?
What is your way ?:)

Answer 7

the answer is: (m+5)(m-3)

which gives m = -5 or m = 3

Answer 8

you can check these types of questions by subbing in your answers back into the original question, and is the left hand side and right hand side of the = sign are the same then you are right

Answer 9

I want your way !

Answer 10

thank you!

Answer 11

let me know if u need the working out part :)

Answer 12

I do, just so I know I understand it cuz I have to do another problem like it

Answer 13

15/m-m=10-8

(15/m) - m = 2

(15/M) - M - 2 = 0

now we are going to multiply all 3 terms by 'm'

(15M/M) - m^2 - 2M = 0

so i will just re arrange it by taking everything to the otherside to make em positive numbers m^2 +2M - 15 =0

Have you seen equations like this be4?

i

Answer 14

Yes

Answer 15

so u know how to factorise them?

Answer 16

Yup

Answer 17

good :P

Answer 18

thanks again!

Answer 19

anytime
