ax+by=c, y=? PLEASE HELP

Nnesha (nnesha):

that's a standard form of slope equation to solve for y you need to move the `ax` and `b` to the right side how would you cancel out ax from left side ? would you subtract add divide or multiply ?

OpenStudy (anonymous):

the problem says to rewrite the equation for y

Nnesha (nnesha):

yes that's what we are going to do!

OpenStudy (anonymous):

ok

OpenStudy (anonymous):

divide

Nnesha (nnesha):

no

Nnesha (nnesha):

it's ax `+` by ax is positive at left side to cancel it out apply the opposite of `addition`

OpenStudy (anonymous):

subtraction

Nnesha (nnesha):

yes right subtract ax both sides let me know what you get

OpenStudy (anonymous):

by=c-ax

Nnesha (nnesha):

yes right! now how would you cancel out the `b` from left side remember it's b ` times` y

OpenStudy (anonymous):

so divide b

Nnesha (nnesha):

perfect!

Nnesha (nnesha):

yes divide by b let me know what you get

OpenStudy (anonymous):

y=ax/b

OpenStudy (anonymous):

THANKYOU

Nnesha (nnesha):

wait what who kidnapped the variable `c` ?

OpenStudy (anonymous):

y=c-ax/b

Nnesha (nnesha):

looks good!

OpenStudy (anonymous):

thx

Nnesha (nnesha):

y = (c-ax)/b put the parentheses to show that c-ax is divide by b not just ax

Nnesha (nnesha):

you're welcome!
