To solve the equation $\frac{3}{2x-1}=\frac{6}{x+7}$, we can cross-multiply to get rid of the fractions:<br /><br />$3(x+7) = 6(2x-1)$<br /><br />Expanding both sides, we have:<br /><br />$3x + 21 = 12x - 6$<br /><br />Combining like terms, we get:<br /><br />$9x = 27$<br /><br />Dividing both sides by 9, we find:<br /><br />$x = 3$<br /><br />Therefore, the correct answer is A. $x=3$.
