Respuestas a la pregunta
Explicación paso a paso:
■ 10x - 10 = 5(x + 2)
10x - 10 = 5x + 10
10x - 5x = 10 + 10
5x = 20
x = 4
■4(x + 10) = 2(x + 22)
4x + 40 = 2x + 44
4x - 2x = 44 - 40
2x = 4
x = 2
■ 4(x + 5) = 2x + 34
4x + 20 = 2x + 34
4x - 2x = 34 - 20
2x = 14
x = 7
■ 6(x + 5) = 7x + 25
6x + 30 = 7x + 25
30 - 25 = 7x - 6x
5 = x
x = 5
