@ganeshie8 help:)

OpenStudy (anonymous):

i tried and got can not be determined

ganeshie8 (ganeshie8):

use the same formula : median = (top + bottom) / 2

ganeshie8 (ganeshie8):

x+12 = (17 + 5x-14) / 2 solve x

OpenStudy (anonymous):

its quite different do i subtract 17 and 14 ?

ganeshie8 (ganeshie8):

yup

OpenStudy (anonymous):

x+12=(13+5x)/2?

OpenStudy (anonymous):

i mean 3+5x

ganeshie8 (ganeshie8):

thats right ! keep going :)

ganeshie8 (ganeshie8):

x+12 = (17 + 5x-14) / 2 x+12 = (3 + 5x) / 2

ganeshie8 (ganeshie8):

wat wud be the next step /

OpenStudy (anonymous):

7

OpenStudy (anonymous):

how would i divide the 2 in x+12?

ganeshie8 (ganeshie8):

next we multiply 2 both sides

ganeshie8 (ganeshie8):

@husseinbzeih u wana explain her/him how to simplify ? :)

OpenStudy (anonymous):

him haha

ganeshie8 (ganeshie8):

lol ok you're a him :)

OpenStudy (anonymous):

2(x+15) equals 3+ 5x

OpenStudy (anonymous):

sry 2(x+12)

OpenStudy (anonymous):

2x+24 equals 3+5x

OpenStudy (anonymous):

3x equals 21

OpenStudy (anonymous):

x equals 7

OpenStudy (anonymous):

right

OpenStudy (anonymous):

Do you want anything else :)

OpenStudy (anonymous):
