If y-18=14, then what is the value of 3(y+5)

Y-18=14
Well, to start off, what is y?
Move 18 to the other side

y-18=14
 +18+18
thus, 

y=32

Then just plug n chug, into the second equation

3(32+5)
distribute the 3
3*32=96
3*5=15
then add what you have multiplied out
96+15=111

Thus, the value of 3(y+5)= 111.
