Answer:
x=-3
Step-by-step explanation:
The quadratic function 
determines the parabola which has the vertex at point (-3,5). The axis of symmetry passes through the vertex and is parallel to the y-axis. Hence, its equation is x=-3 (see attached diagram).
Answer:
y = t/31 - d/31
Step-by-step explanation:
Solve for y:
d + 12 y = t - 19 y
Subtract d - 19 y from both sides:
31 y = t - d
Divide both sides by 31:
Answer: y = t/31 - d/31
