Question

Which of the following is equivalent to

Answer 1

the third one

Explanation:

`\frac{5x+2}x=(-12)/(x-1)\\\\{}\quad\ \cdot x\qquad\ \cdot x\\\\5x+2\ =\ (-12x)/(x-1)\\\\\cdot (x-1)\quad \cdot (x-1)\\\\(5x+2)(x-1)=-12x`

Answer 2

Answer: C

Explanation:

This is the answer because you have to multiply (x-1) on both sides and that will cancel out the denominator on the right. Then, multiply by x on both sides and that will cancel the denominator on the left side. When you do this, C should be your answer. Hope this helps :)
