Question

Calcule o valor das equações abaixo usando a propriedade distributiva.

a) 2(x – 4) = x + 8

b) 3x + 4.(1 + x) + 2 = 5x – x – 6

c) 5.(3x - 2) = 2.(6x + 3)

d) 7.(x-1) = 2.(3x+1)

e) 2.(x - 2) + 5.( 2 - x) + 6.(x + 1)= 0

f) x - (x + 1) = 12 - (3x - 2)

h) 3.(x + 3 ) – 5 = 22 i) 3( x + 2 ) = 2 ( x – 7)

j) 4(2m-1) + 3m = 2(4m-1) – (2 –m)

k) 3(x + 2 ) – 1 = 2(x + 3) – 7 l) 3(2x – 3 ) + x = 5

l) 3(2x – 3 ) + x = 5

m) 2 ( x – 1 ) + 3(x + 1 ) = 4(x + 2)

n) 5 (2x – 1 ) = 3 (x + 10)

o) 3. (x +2) + 5 = x + 12

p) x + 4.(x - 1) = 9 - 2.(x + 3)

q) 2.(3x-1) + 2 .(3-x)= 0

r) 2.(3 - y) + 7.(2 - y) = 15 - 4y

s) 3. (x - 2) - (1 - x) = 13

t) 2.(x + 5 ) – 4 = 26

u) 2.(2x + 7 ) + 3.(3x – 5 ) = 3.(4x – 5 ) – 1

v) 4(2x –1 ) = 3( x+2 )

w) 3(x + 3 ) - 1 = 2

x) 3(x + 1 ) + 2 = 5 + 2(x - 1 )

y) 3x + 5 + 2x + 6= x + 27

z) 3(3x +8) -5x = x - 3

z1) 2(x – 3 ) + 8x +4 = 5 (x + 2 )
