Question

a)The sum of two numbers is 40. Taking the numbers as x and y from an equation b)Their difference is 10 . Using this idea from another equation c)Find the numbers​

Answer 1

Answer:

Thus x - y = 10 is the same as (40 - y) - y = 10. This is equal to 40 - 2y = 10. We then move around the numbers in the equation to get 2y = 30.

Answer 2

Step-by-step explanation:

let the number be x and y

According to question

x+y= 40

x-y = 10

Adding these equation, we get

2x= 50

x = 50/2= 25

so 25+y= 40

y= 40-25=15
