Answer:

The Solution is x=78 and y = 64

Step-by-step explanation:

The sum of two numbers, x and y, is 142.

So, x+y=142 ---- 1

We are given that their difference is 14.

So, x-y=14 ---- 2

Add 1 and 2

2x=142+14

2x=156

[tex]x=\frac{156}{2}[/tex]

x=78

Substitute the value of x  in 2

So,78-y=14

78-14=y

64=y

Hence The Solution is x=78 and y = 64
