Question

I need help with this question Picture is attached!!!!

Answer 1

Move everything that is not a y to the other side of the equals sign.

Answer 2

Another strategy is to take all the answer choices and put them in the form Ax+By=C and see which ones match.

Answer 3

what happens to the 15?

Answer 4

You can leave it where it is for now. In some of the possible answers, it has been simplified by division, and in others it has not.

Answer 5

so far i got 5 3 2

Answer 6

What do those numbers represent, 5, 3, 2?

Answer 7

the numbers of the answers

Answer 8

Some of those don't check out.
What strategy are you using? Are you solving the given equation or working backwards from the answer choices?

Answer 9

well i was using the ones with 3/5 for 15 and 3x

Answer 10

I have been stuck on this problem for awhile

Answer 11

Ah.
Here's one way to solve for y.
Give 3x+5y=15
Subtract 3x
5y=15-3x
Divide by 5
y=(15-3x)/5
There are a couple different ways to simplify that last line.

Answer 12

Alright i think i got it 4, and 5

Answer 13

There is at least one more that works.

Answer 14

got it! its the 4th one to righ @CliffSedge

Answer 15

Look at the 4th an 6th, they are commutative.

Answer 16

awhh ok i see its not the 5th one cuz it 3/5 and 15/5

Answer 17

No, 5th is fine, that was the original form of the solution that I showed.
