Answer:
y=9
Step-by-step explanation:
First we need to solve al addition and subtraction by performing the inverse operation. In this case, we need to add to reverse the subtraction
y/3 -4= -1
y/3= 3
Now we solve all multiplication and division again using the inverse operation, which in this case is multiplication, because the variable is being divided.
y/3=3
y=9
Thus we get that the value for y is 9.
