Answer 1

Answer:

Hello there!

Step-by-step explanation:

let a & b be two numbers.

a+b= 29

a-b= 5

Adding both the equations.

2a= 34, a=17

put the value of a in above eqn, we get b= 12

Tip: always try to eliminate 1 variable

Hope it helps.

Answer 2

ans

let x and y be the number

eq.1 sum of two number is 29

x + y = 29

eq2 their difference is 5

x - y = 5

solving the two equations we have

x + y = 29

x - y = 5

------------------

2x = 34

x = 17 (answer)

from

x - y = 5

17 - 5 = y

y = 12 (answer)

so the numbers are

12 and 17 (answer)
