solve for y in terms of x?

Question

i'm completely lost on this problem.

the equation is

2x-3y=12

please help me. its confusing me so much

how do i solve for y. please give me step by step answers so i can understand better.

thank you !!!

Answer 1

2x-3y=12

Subtract 2x from both sides

-3y = 12 - 2x

Divide thru by 3

-y = 4 - (2/3)x

Multiply both sides by -1

y = -4 + (2/3)x or y = (2/3)x - 4
.

Answer 2

1. 2x=12+3y ( add 3y to both sides)

2. 2x-12=3y ( subtract 12 from both sides)

3. 2/3x -4=y (divide by 3 to both sides)

4. Voila!

Answer 3

ok
here's how it works
it's basically a two part problem

in the first problem you substitute X for 0 so it's 2(0)-3y=12
and then it ends up as [Y=-4]
the second problem you have to substitute Y for 0 and so it's
2x-3(0)=12 and the answer is [X=6]


i hope this is the kind of problem you're talking about.

if not, sorry.

Answer 4

2x-3y=12
subract 2x from both sides.

-3y= 12-2x
divide both sides by -3.

y= 12/(-3) - 2x/(-3)
reduce.

y= -4+2/3x

Answer 5

2x-3y=12

Subtract 2x from both sides

-3y=12-2x

Divide both sides by -3

y=-4+(2/3)x

You could also write this as

y=(2/3)x-4

Answer 6

2x-3y=12
-2x -2x
-3y=12-2x
make variable positive
3y = -12 +2x
divide by 3
y= -4 +2x/3
that's it :D

Answer 7

2x-3y=12
-3y=12-2x
3y=-12+2x=2x-12
y=(2x-12)/3
y = 2/3x-4

Answer 8

y = (12 - 2x) / -3

Answer 9

Do you recommend resolve for x in terms of y? y = (x^2 + x + 0.25) - one million - 0.25 y = (x + 0.5)^2 - one million.25 y + one million.25 = (x + 0.5)^2 +/- sqrt(y + one million.25) = x + 0.5 +/- sqrt(y + one million.25) - 0.5 = x
