Question

The sum of two numbers is 49 and the difference between these two numbers is 9. What are these two numbers?​Shown working out please

Answer 1

Let numbers be x and y

ATQ

• x+y=49---(1)

• x-y=9---(2)

Adding both

$\\ \sf\longmapsto 2x=58$

$\\ \sf\longmapsto x=\dfrac{58}{2}$

$\\ \sf\longmapsto x=29$

Now putting value in eq(2)

$\\ \sf\longmapsto x-y=9$

$\\ \sf\longmapsto 29-9=y$

$\\ \sf\longmapsto y=20$
