When we say to solve for something
⇒ essentially move everything to one side
⇒ and that 'something' to the other
In this case:
⇒ we need to move the y-variable by itself to one side
⇒ and everything else to the other
Let's apply that principle:
[tex]12y+d=-19y+t\\12y+19y=t-d\\31y=t-d\\y=\frac{t-d}{31}[/tex]
Answer: (t-d) / 31
Hope that helps!
