Answer:

b=4/3

Step-by-step explanation:

Distribute first

6b - 15 = 4 - 3b - 7

6b - 15 = -3b -3, add 3b to both sides

9b - 15 = -3, add 15 to both sides

9b = 12, divide both sides by 9

b = 12/9 = 4/3

Which of the following is the correct answer??
Ahat [919]
The correct answer is C. 

When you have two fractions being divided, you can flip the second one and then multiply straight across. So in this case the top of your final answer would be the numerator of the first fraction multiplied by the denominator of the second:

(3x - 6)(2x - 1) = 6x^2 - 15x + 6

Then the bottom of your answer would be the denominator of the first fraction multiplied by the numerator of the second one:

x^3(x - 2) = x^4 - 2x^3
