Divide by 3:

Write as: (9/10)/(3/1)

whenever you have a fraction divided by a fraction, you multiply the top and bottom by the reciprocal of the denominator (1/3).. this will result in the denominator = 1, so it can be neglected.. and the numerator:

= (9/10)*(1/3) = 9/30

y = 9/30 = 3/10

(note: both sides were negative, so it can be dropped..)

Hey there!

Here's the answer.

-3y=-9/10 --> Write the problem.
3y=9/10 --> Divide both sides of the equation by -1.
y=9/30 --> Divide both sides of the equation by 3.
y=3/10 Simplify the above equation.

So the answer is y=3/10.

Hope it helps!

Neg will cancel on both sides,so we have
3y=9/10
or y=9/10*3
or y=3/10=.3

3y = 9 / 10
y = 3 / 10

3y = -9/10
(-3/1)y = -9/10

y = (-9/10) * (1/-3) -->Multiply straight across.
y = (-9 * 1) / (10 * -3)
y = -9 / -30
y = 3/10

-3y = -9/10
(-3/1)y = -9/10

y = (-9/10) * (1/-3) -->Multiply straight across.
y = (-9 * 1) / (10 * -3)
y = -9 / -30
y = 3/10

5x=10
x=2
but you can multiply them by anything the same and get an answer
by 4
20x=40
x=2

multiply a negative by a negative to make it positive
on both sides
times -1
3y=9/10
now it is friendlier
ignore 10 and just divide 3 into 9
y=3/10
