Question

Write down a pair of integers whose:
(a) sum is -7 (b) difference is -1​

Answer 1

Answer:

-3, -4

Step-by-step explanation:

x+y=-7 and x-y=-1

->y-1+y=-7

=>y=-3

=>x=-4

Answer 2

Answer: the two integers are -4 and -3

Step-by-step explanation:

x+y=-7

x-y=-1

adding this two equations, ie x+y+x-y=-7+-1

ie, 2x=-8, ie, x=-8/2=-4

ie -4+y=-7

ie, y=-7+4=-3

So x=-4 and y=-3
