Question

whats the value of y?
4y+15=6y-45

Answer 1

To solve for y, you need to isolate y.
That means, subtract 6y from both sides to have all y-terms on the left side.
Also, you need to subtract 15 from both sides to bring all numbers to the right side.

Answer 2

Start by doing the two steps above.
What do you get?

Answer 3

subtract 15 from both sides and 6y from both sides to get -2y=-60 then divide by negative 2.

Answer 4

-30 ?

Answer 5

Negative divided by negative is positive.

Answer 6

no, because a negative divided by a negative is a positive.

Answer 7

so a negative 60 divided by a negative 2 should be what?

Answer 8

30

Answer 9

correct

Answer 10

\(4y+15=6y-45\)

Subtract 6y from both sides:

\(-2y + 15 = -45\)

Subtract 15 from both sides:

\(-2y = -60\)

Divide both sides by -2:

\(\dfrac{-2y}{-2} = \dfrac{-60}{-2} \)

\(y = 30\)
