Question
For each system find the values of a and b so that the solution set to the system is $\{(5,12)\}$$$\begin{aligned}&y=3 x+a\\&y=-2 x+b\end{aligned}$$
Step 1
This means that when we substitute $x=5$ and $y=12$ into the equations, they should hold true. Let's start with the first equation $y=3x+a$. Substituting $x=5$ and $y=12$ we get: \[12 = 3(5) + a\] Show more…
