Question

1) Resolva as equações do 1º grau:
a) y – 3 = - 4y + 7
b) – x – 2x – 4 = 11 – 2x + 4x
c) 9 – x + 2 = - 5x + 37
d) 4x – 3 – 2x = - 20 – 3 – 2x
e) 3(x + 10) – 2(x – 5) = 4 – 5x
f) 2(x – 6) = - 3(5 + x)
g) 3(x – 1) – 2(x – 4) = 1
h) 9y – (4 – 9y) = - 12
i) 7(x – 1) – 2(x – 5) = x - 5
j) 3x/4 - x/2 = - 2
k) x/3+ x/2=7+X/3
l) 3x/9= 2 + 2x/3
m) 2(y – 3) + 4 = - 2y + 6
n) 10 – 2(3x + 1) = 5 + 3(x - 5)
