Question

P+q=-2 p-q=8 Elimination using Add and Subtraction

Answer 1

Answer:

p+q = -2 ----- equation 1

p-q = 8 ------ equation 2

Adding both equations

p+q+p-q = -2+8

2p = 6

p = 6/2

p = 3

Subtracting equation 2 from equation 1

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

p+q-p+q = -10

2q = -10

q = -10/2

q = -5

p= 3

q = -5
