Dividing two fractions is the same as multiplying the first fraction by the reciprocal (inverse) of the second fraction.
Take the reciprocal of the second fraction by flipping the numerator and denominator, leaving the negative sign on the numerator, and changing the operation to multiplication. Then the equation becomes
For fraction multiplication, multiply the numerators and then multiply the denominators to get
This fraction can be reduced by dividing both the numerator and denominator by the Greatest Common Factor of 9 and 12 using
Answer:
Step-by-step explanation:
Given:
To solve for y, let us first isolate y on one side of the equation. We can do this by subtracting from the left and move it to the right. We then get:
Now, we have y isolated. We now have to remove the 4 from the y. The only way to do this is divide both sides by 4. We then get our final answer:
We can clean this up by putting it in a common form, slope-intercept form:
