Explicación paso a paso:
a) 2x + 6 = 8
2x = 8 - 6
2x = 2
x = 2÷2
x = 1
b) 7x - 2 - 4 = 50
7x - 6 = 50
7x = 50 + 6
7x = 56
x = 56 ÷ 7
x = 8
c) 6x + 3 = x - 7
6x - x = - 7 - 3
5x = -10
x = -10 ÷ 5
x = -2
d) 3x + 3 = 4x + 4
3x - 4x = 4 - 3
-x = 1
x = 1 ÷ -1
x = -1
2x + 6 = 8
x = 2/2
7x - 2 - 4 = 50
7x = - 6 = 50
x = 56/7
