Question

Find those two numbers whose sum is 5 and whose difference is 3

Answer 1

Answer:

4,1

Step-by-step explanation:

4+1=5(two numbers whose sum should 5)

4-1=3(two numbers whose difference should 3)

Answer 2

Answer:

the two numbers are 1 and 4

Step-by-step explanation:

let those two numbers be x, y

$x + y = 5 \\ x - y = 3$

$(x + y) + (x - y) = 5 + 3 \\ x + y + x - y = 8 \\ 2x = 8 \\ x = \frac{8}{2} \\ x = 4$

$x + y = 5 \\ 4 + y = 5 \\ y = 5 - 4 \\ y = 1$
