A strong acid is a number between 0-6 on the pH scale and Bases are between 8-14 on the pH scale the difference is how much hydroxide each one has like coca-cola (acid) and backing soda (base)
U_____________W________________V
UV=13
UW=2y-9
WV=y-5
UV=UW+WV
UV=(2y-9)+(y-5)=2y-9+y-5=3y-14
13=3y-14
27=3y
y=27/3=9
Solution is A, y=9
