Find the ordered pair (s, t) that satisfies the system

\(\begin{align*} \dfrac{s}{4} - 2t &= 2,\\ 3t - 6s &= 9. \end{align*}\)

Multiply first equation by 24

-48t +6s = 48 add it to the second equation

3t - 6s = 9 to get

-45t = 57 divide both sides by -45

t = -57/45 = -1 12/45 = -1 4/15 now substitute this value of t back into one of the two original equations and solve for 's'
