we need to isolate y right? so we need to subtract 3x from both sides now we have \[\huge~\rm-2y=-3x+12\] any cles on what the next step is?

the next step is to divide the left side by -2.

I got -2y/-2 = 12-3x/-2 and then y = -6 -3x/-2 and the final answer is y = -6 - 3x/2. Is this correct?

-6? where did that come from?

  • Amenah8
I got -6 by doing 12/-2.

\[\huge~\rm~\frac{ −2y=−3x+12 }{ -2y=-2y-2y}\]

I did that except I didn't have it divided by -2y, I had -2 without the y.

keep in mind, when dividing by 2 negatives, the result is positive

y=-3/2x-6

Ah, so that means that the answer would be a positive -6+3x/2.
