A)3x - 2 + 7x = 7 - 1
10x = 8
x = 8 / 10
x = 4 / 5
b)4(2x + 3) - 2x = 4x + 20
8x + 24 - 2x = 4x + 20
2x = - 2
x = - 1
c)34 = 3x - 6 + 2x
40 = 5x
x = 8
d)3(1 - 2x) + 12 = 10 - 2(x - 3)
3 - 6x + 12 = 10 - 2x + 6 - 1 = 4x
x = - 4
E) 4(X - 6) = 12 - (X + 3)
4x - 24 = 12 - x - 3
5x = 33
x = 33 / 5.
4x + 3 = 2x + 9 4x - 2x = - 3 + 9 2x = 3 ___________________________________________________________ (5x / 2) + 2 = 20 + 2 (5x / 2) = 20 + 2 - 2 5x = 2(20) x = 40 / 5 x = 8…
Te voy a dar un ejemplo para que te sea mas facil : x + 2 : 4 x : 2 - 4 x : 2.
