Answer 2

A) 7x - 15 = 20
7x = 20 + 15
7x = 35
x = $\frac{35}{7}$
x = 5

B) -5x - 8 = 12
-5x = 12 + 8
-5x = 20
x = $-\frac{20}{5}$
x = - 4

C) 4x - 10 = 26
4x = 26 + 10
4x = 36
x = $\frac{36}{4}$
x = 9

D) -6x - 18 = 10
-6x = 10 + 18
-6x = 28
x = $-\frac{28}{6}$
x = $-\frac{14}{3}$ <---- Se ha simplificado: 28 ÷ 2 = 14 y 6 ÷ 2 = 3
