Question

b) 2 ( 9x - 4) - 7 + ( 6 - 5x). 3 = 18​

Answer 1

Resposta:

Resolva as equações, sendo U = Q:

a) 4x – 1 = 3(x – 1)

b) 3(x – 2) = 2x - 4

c) 2(x – 1) = 3x + 4

d) 3(x – 1) – 7 = 15

e) 7(x – 4) = 2x - 3

f) 3(x – 2) = 4(3 – x)

g) 3(3x – 1) = 2(3x + 2)

h) 7(x – 2) = 5(x + 3)

i) 3(2x – 1) = -2(x + 3)

j) 5x – 3(x + 2) = 15

k) 2x + 3x + 9 = 8(6 – x)

l) 4(x + 10) – 2(x – 5) = 0

m) 3(2x + 3) – 4(x – 1) = 3

n) 7(x – 1) – 2(x – 5) = x - 5

o) 2(3 – x) = 3(x – 4) + 15

p) 3(5 – x) – 3(1 – 2x) = 42

q) 4x + 6 – 2x = x – 6 + 10 + 14

r) x – 3 – (x + 2) + 2(x – 1) – 5 = 0

s) 3x – 2(4x – 3) = 2 – 3(x – 1)

t) 3(x – 1) – (x – 3) + 5(x – 2) = 18

u) 5(x – 3) – 4(x + 2) = 2 + 3(1 – 2x). ajuda pelo menos umas 6 ou 5
