Question

sum of 2 number (a + b) is 35 and difference between the is (a-b) is 19. find the product

Answer 1

a+b=35

b=35-a

a-b=19

a-(35-a)=19

a-35+a=19

2a=19+35

a=54/2

a=27

a+b=35

27+b=35

b=35-27

b=8

ab = a*b = 27*8 = 216

Answer 2

Answer:

a+b+a-b=35+19 (1)

2a=45

a=45/2

then put the value of a:

22.5+b=35

b=12.5 (2)

Now, put both value a and b:

12.5*22.5
