Q: With the following two equations, find the value of $\displaystyle u$:

$\displaystyle 2ut = 735 \ \ \ \ \ \ \ \ \ \ \ \ \dots (1)$

$\displaystyle 0 = 3ut - 21 gt^2\ \ \ \ \dots (2)$.

The correct answer is $\displaystyle u=24.5$. I'm getting an incorrect answer. Can someone do this question and see if they obtain the correct answer so I can compare with mine. Thanks in advance.
