Multiply the whole equation times any denominator.
OpenStudy (trojanpoem):
Do with me step by step.
OpenStudy (anonymous):
so... im not sure how to do that would i multiply each number individually or as a group? im really confused, sorry
OpenStudy (trojanpoem):
Multiply each term times the denominators
in our case only 3 is denominator so
3y = -2x + 21
Now get y ,x in same side:
3y + 2x = 21
Ay + Bx = C
DONE!
OpenStudy (anonymous):
y= -2/3x + 7
y(3) = -2/3x(3) + 7(3)
3y = -2x +21

so those are the steps?
OpenStudy (anonymous):
wait so my answer options are 2x + 3y =21,
3x-2y =21,
-2x -3y=21,
-2x +3y +7
OpenStudy (anonymous):
would it be 2x +37 =21?
OpenStudy (trojanpoem):
yes.
