(1 - 7x) - 2x = r relação I
(3x - 11) - (1 - 7x) = r relação II
fazendo relação I = relação II, temos
(1 - 7x) - 2x = (3x - 11) - (1 - 7x)
1 - 9x = 3x - 11 - 1 + 7x
1 - 9x = 10x - 12
1 + 12 = 19x
19x = 13
x = 13

[(2x) + (3x – 11)]/2 = (1 - 7x)
[(2x) + (3x – 11)] = 2 . (1 - 7x)
[5x – 11] = 2 - 14x
(5x + 14x) = (2 + 11)
19x = 13
X = 13/19
