15 over 7y=3
y = 6 3/7
15 over 7y=3
15/(7y) = 3
21y = 15
y = 15/21
y = 5/7
Reiny's right.
To solve the equation 15 over 7y = 3, you need to isolate the variable y. Here's how you can do it:
Step 1: Start by multiplying both sides of the equation by 7y to eliminate the denominator.
(15/7y) * 7y = 3 * 7y
The 7y on the left side cancels out with the denominator, leaving:
15 = 21y
Step 2: Next, isolate y by dividing both sides of the equation by 21.
15/21 = 21y/21
On the right side, the 21y/21 simplifies to just y, as the 21s cancel out:
15/21 = y
Step 3: Simplify the fraction, if possible.
15/21 can be simplified by dividing both the numerator and the denominator by their greatest common divisor, which is 3 in this case:
15 ÷ 3 / 21 ÷ 3 = 5/7
Therefore, the solution to the equation 15 over 7y = 3 is y = 5/7.
