Which eqation is equivalent to 3x + 4y = 15
a) y=15-3x

4
b) y=3x-15

4
c) y=15-3x
d) y=3x-15

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
