Question

the sum of two numbers is 110. Their difference is 28. What is the smallest of the two numbers?

a.56
b.41
c.69
d.55

Answer 1

x+y=110
x-y=28
Can you see it now?

Answer 2

So you have two variable a and b that follow the following equations:
a+b = 110
and
a-b = 28
Therefore, you can say
(a + b) - (a - b) = 110 - 28
Work this out and you'll get the answer.

Answer 3

i got 82

Answer 4

110-41=69 69-41=28

Answer 5

41 is the correct one

Answer 6

b

Answer 7

x + y = 110
x - y = 28
2x = 138
x = 69
So, 69 and 69-28 = 41 are answers

Answer 8

41 is the final answer
