@3mar

jhonyy9 (jhonyy9):

bc. how ve wrote above the diagonales are congruent - so make this expressions equal and try solve it for y

jhonyy9 (jhonyy9):

6y-1 = 4y+13

OpenStudy (devonhoward15):

i know that... the hard part is finding the number

jhonyy9 (jhonyy9):

ok. so please show your work for y value

OpenStudy (devonhoward15):

i have to find the number

jhonyy9 (jhonyy9):

6y-1 = 4y+13 subtract from both sides 4y so what will get ?

OpenStudy (devonhoward15):

2y-1=4y+9?

jhonyy9 (jhonyy9):

why so ? not is right

OpenStudy (devonhoward15):

idk if its right

jhonyy9 (jhonyy9):

6y-4y-1 = 4y-4y +13

OpenStudy (devonhoward15):

you said subtract 4 from each side... you subtracted 2

jhonyy9 (jhonyy9):

no i ve subtracted 4y from both sides 6y-4y -1 = 4y-4y +13 ok. ?

OpenStudy (devonhoward15):

umm ok

jhonyy9 (jhonyy9):

please continue

OpenStudy (devonhoward15):

I HAVE NO IDEA HOW TO DO THIS!! @3mar

jhonyy9 (jhonyy9):

why ? 6y-4y = ?

OpenStudy (devonhoward15):

2y?

jhonyy9 (jhonyy9):

= 2y and on the right side 4y-4y = 0 yes ?

OpenStudy (devonhoward15):

yes

jhonyy9 (jhonyy9):

so will get 2y-1 = 13 now add to both sides 1 so what will get ?

jhonyy9 (jhonyy9):

2y-1+1=13+1

OpenStudy (devonhoward15):

ok

jhonyy9 (jhonyy9):

2y=14 divide both sides by 2 and will get ?

OpenStudy (devonhoward15):

1y=7

jhonyy9 (jhonyy9):

yes sure y=7

jhonyy9 (jhonyy9):

so this is clearly now ?

jhonyy9 (jhonyy9):

ok. was my pleasure good luck bye bye

OpenStudy (devonhoward15):

a little more clear... next question now
