sum of two number and the difference of the two are 498 and 302 respectively .Find the numbers
Answers
Answer:
Lets assume that numbers as x and (x-302)
The sum of the numbers are 498
Therefore
x+(x-302) = 498
Lets remove the brackets
x+x-302 = 498
x+x = 498 + 302
2x = 800
x = 800/2
= 400
x-302 = 400 - 302
= 98
So the numbers are 400 and 98
Sum = 400 + 98 = 498
Difference = 400 - 98 = 302
Given that: Sum of two number and the difference of the two are 498 and 302 respectively. Means,
- Sum of 2 numbers = 498
- Difference of 2 numbers = 302
To find: The original numbers.
Solution: 98 and 400 are the original numbers.
Assumption: Let the two numbers be x and y respectively. Means,
- 1st number is x
- 2nd number is y
Full Solution:
~ As it's said that
- Sum of 2 numbers = 498
- Difference of 2 numbers = 302
Henceforth,
- x+y = 498...Equation 1
- x-y = 302...Equation 2
- (Now we have to add ...Equation 1 and ...Equation 2 together)
- (Remember, LHS will with LHS and the RHS will add with RHS)
››› x+y+(x-y) = 302+498
››› x+y+x-y= 302+498
- (- = + or + = -)
- (- and + cancel each other)
››› x+x = 302+498
››› 2x = 302+498
››› 2x = 800
››› x = 800/2
- (÷ = × or × = ÷)
››› x = 400
Henceforth, the values of x we get as 400. 400 is 1st number
››› 400+y = 498
››› y = 498-400
››› y = 98
Henceforth, the values of y we get as 98. 98 is 2nd number
