Answer 1

$\huge\fbox\pink{ANSWER:}$

Step-by-step explanation:

a+b= -15

a-b= -25

b= -15-a

put the value of b

a-b= -25

a-(-15-a)= -25

a+15+a= -25

a= -20

b= -15-20

b= -35

Answer 2

$\huge\fbox\pink{✯Answer✯}$

let that integers be x and y.

• From 1 st condition
• x+y = -15 (1)

• From 2 nd condition
• x-y=-25 (2)

Therefore,

• x+y = -15
• y=-15-x

Place the value of y=-15-x in (2)

• x-(-15-x)=-25

• X+15+X=-25

$X=-20$

y=-15-20

$y=-35$
