OpenStudy (plasmataco):

k...

OpenStudy (plasmataco):

it's a system

OpenStudy (anonymous):

okay

OpenStudy (plasmataco):

6x+4y=534 and 7x+3y=513

OpenStudy (anonymous):

yep i got that

OpenStudy (plasmataco):

now multiply the bottom equation by 4 and multiply the top equation by 3

OpenStudy (anonymous):

what do you mean bottom is that 6x+4y=534 and top the other one?

OpenStudy (plasmataco):

so turn the bottom one to 28x+12y=2052

OpenStudy (plasmataco):

and turn ur top one to 18x+12y=1602

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

okay so i solved for the x's and ys do i add them together ?

OpenStudy (plasmataco):

subtract the 2 equations to get 10x=450

OpenStudy (plasmataco):

x=45

OpenStudy (anonymous):

oh ok

OpenStudy (plasmataco):

plug it in to you first equation and u should get 66

OpenStudy (plasmataco):

45 per bracelet, 66 per necklace
