Answer
A
Work Step by Step
For cross multiplication, we know:
$$\frac{a}{d} =\frac{b}{c} \rightarrow ac=bd$$
Thus, we find:
$$3\left(x-1\right)=\left(x+2\right)\cdot \:6\\ 3x-3=6x+12\\ x=-5$$
Checking our solution by plugging the given value back into the equation, we assure that the solutions are not extraneous.
