Question

2) Resolva as equações:
a) X + 30 = 40
b) 30 -20 + 2x = 10
c) 3x - 10 + 13 = -2x + 28
d) 20x - 30 = 40 + 30 - 20
e) -5x + 45 -89 = -90 +41
f 10x - 20 = 40 + 50
a) 20-80 + 2x = 10
h) 19 + 2x - 13 = 10-20
1) 10 - 12 + 10 = 18-20
1) 8 (x + 2) = 4(x + 6)
k) 8 (x + 3) = 40

m) 10 (2x - 1) = 4(x + 4)
n) 4x-6 (4- x) = 10 + 8 (2x + 1)
o) 10x - 20 (x - 1) = 40 - 30 (x-2)
p) 2 (3x - 7) + 3 (x-1) = 4 (2x - 3)
q) 6 (x-3) + 12 (2x + 1) = 24 - 15 (x-4)q)
r) 6x = 2x + 16
s) 2x - 5 = x + 1
t) 2x + 3 = x + 4
u) 5x + 7 = 4x + 10
v) 4x - 10 = 2x + 2
w) 4x - 7 = 8x - 2
x) 2x + 1 = 4x - 7
y) 9x + 9 + 3x = 15
