Answer:
B
Step-by-step explanation:
THis is a single equation with a single variable [y].
We can separate the variable in one side and the numbers to another and solve for y. Shown below:
3y + 4 = -2
3y = -2 - 4
3y = -6
y = -6/3
y = -2
THus, this equation has only 1 solution. B is correct
Remark
Writing down the givens for these questions is almost a command. You must know which equation of the big 4 to use. The givens + what you want to find will determine the equation.

vi = 30.7 km/hr = 30.7 km/hr *[1000m/1km]*[1hr/3600sec] = 8.52m/sec
vf = 120 km/hr = 120 km/hr * [1000 m/1 km]*[1h/3600 sec] = 33.3 m/s
t = 4.9 seconds
d = ???
Formula
d = (vi + vf)*t/2
Solve
d = ( 33.3+8.52 )*4.9/2
d = (41.85333)*4.9/2
d = 205.02/2
d = 102.51 m<<<Answer
