63+12x<15
12x<-48 (subtract 63 from both sides)
x<-4 (divide out the 12)

You just times it. (if you have a more question pm me). thank you
w-(-3)=7
Pretend that there is a -1 in front of the bracket
w-1(-3)=7
Mutiply the bracket by -1
(-1)(-3)=3
w+3=7
Move +3 to the other side. Sign changes from +3 to -3.
w+3-3=7-3
w=4
Answer: w=4
