Question

Resolva as seguintes equações
a) 4x – 1 = 3 ( x – 1)
b) 5( x – 3 ) – 4 ( x + 2 ) = 2 + 3( 1 – 2x)
c) 3( x – 2) = 2x – 4
d) 3( x- 1) – ( x – 3) + 5 ( x – 2) = 18
e) 2( x – 1) = 3x + 4
f) ( x – 3) – ( x + 2) + 2( x – 1) – 5 = 0
g) 3(x – 1) – 7 = 15

Answer 1

Resposta:

Explicação passo a passo:

a) 4x = 3+1

4x=4

x=4/4

x=0

b) 5x -15 -4x -8= 2+3-6x

5x -4x +6x= 15+8+2+3

15x= 28

x= 28/15

c) 3x -6 = 2x -4

3x -2x= 6-4

x=2
