A. 9V7 -2V28-5V63 = 9V7 -2V(4*7) -5V(9*7) = 9V7-2*2V7-5*3V7 = 9V7-4V7-15V7 = -11V7

b. V24+V54-V150 = V(4*6)+V(9*6)-V(25*6) = 6V6+3V6-5V6 = 4V6

c. 2V50 -V98 -V18 = 2V(25*2)-V(49*2)-V(9*2) = 2*5V2-7V2-3V2 = 10V2-7V2-3V2 = 0V2 = 0

d. 5V20+4V45-V80 = 5V(4*5)+4V(9*5)-V(16*5) = 5*2V5+4*3V5-4V5 = 10V5+12V5-4V5 = 18V5
