Question

if a+b+c+d=14 , a+c+d=8 and a+d=7 then the value of a+c= ?​

Answer 1

Answer:

a+b+c+d=14 and a+c+d=8

subtracting both we can get the value of b so....

a+b+c+d-a-c-d=14-8

b=6

a+b+c+d=14 and a+d=7

so subtracting both we can get b+c and putting the value of b we can get the value of c so....

b+c=14-7=7

c=7-6=1
