ANSWER:
a. y = -14
b. x = -4
STEP-BY-STEP EXPLANATION:
We have the following formula:
[tex]y=3x+1[/tex]
We solve in each case:
[tex]\begin{gathered} y=3x+1 \\ \\ (a)\text{ }x=-5 \\ \\ y=3(-5)+1=-15+1=-14 \\ \\ (b)\text{ }y=-11 \\ \\ -11=3x+1\: \\ \\ 3x=-11-1 \\ \\ x=\frac{-12}{3}=-4 \end{gathered}[/tex]
