Resolver mediante método de suma

3p + 2q = 11

2(4q - r) = (6)2

8q - 2r = 12

2p + 2r = 2 - - - - - - - - - - - -

8q + 2p = 14

3p + 2q = 11

10q + 5p = 25

5(p + 2q) = 25

(p + 2q) = 25 / 5

(p + 2q) = 5 - 1(p + 2q) = 5 - p - 2q = - 5

3p + 2q = 11 - - - - - - - - - - - - -

2p = 6

p = 3 , , , , , , , (p + 2q) = 5 3 + 2q = 5 2q = 5 - 3 2q = 2 q = 1

2p + 2r = 2

2(p + r) = 2

p + r = 1

3 + r = 1

3 - 1 = - r

2 = - r - 2 = r.
