Answer 2

Answer:

X = 6

Step-by-step explanation:

Cross Multiplication

We can go about this 1 of 2 ways we can either cross multiply or divide across the numerators and denominators. Let's cross multiply. We would 4*9 = 6x. Which would simplify down to 36 = 6x. We would then divide the 6 on each sides of the equation to get 6 = X.

Dividing Across

The other way we can go about it is by seeing what 4 had to be multiplied by to get to 6. We do this by dividing 6 by for which gets us 3/2 or 1.5. Now that we know this we would then divide 9 by 3/2 or 1.5 to get the answer of 6.
