Question

The sum of two numbers is -63 the first number minus the second number is -41 find the numbers

Answer 1

x = -52

y = -11

Explanation:

Let 1st number = x

Let 2nd number = y

Hence:

x+y=-63

x-y=-41

y = x+41

(Apply Simultaneous Equations)

x+(x+41)=-63

2x+41=-63

2x=-63-41

2x=-104

x=-104/2

x=-52

Now:

y=-52+41

y=-11
