Question
The solution to the following system of equations is $(2,-3)$. Determine $A$ and $B$.$$\begin{aligned}&A x+4 y=-8 \\&3 x-B y=21\end{aligned}$$
Step 1
For the first equation, we have: $A(2) + 4(-3) = -8$ $2A - 12 = -8$ For the second equation, we have: $3(2) - B(-3) = 21$ $6 + 3B = 21$ Show more…
