1) Encontre o valor de x:
a) 8x =
4x +16
b) 2x -7
= x + 5
c) 3x +
5 + x – 5
d) 6x –
8 = 4x +10
e) 8x –
10 = 2x + 2
f) 9x –
7 + 5x +21
g) 12x +
3 = 7x – 25
h) 6x –
4 = 12x + 12
i) 5x –
2 = 2x + 7
j) 16x –
4 = 12x + 2
2) Resolva:
a) 5x – 2 + x = 2x + 10
b) 18x – 7x =
3x + 28
c) x + x – 2 = 17 + 1
d) x + 3x + 3 =
3x – 2
e) 5x + 7x -15 = 17 + 4x
