Question

Can someone help me solve this?

Answer 1

The first one can be -4+2= -2

Answer 2

p + q = (-2) --------(1)

p - q = 8 ----------(2)

on simplifying both equati

8 + q = (-2)-q

q + q = (-2) -8

2q = (-10)

q = (-10)/2

q = (-5)

putting the value of q = (-5) in the equation

p + (-5) = (-2)

p = (-2)+5

p = 3

hence, p = 3 , q = (-5)
