Question

me passem os cálculos plss

Answer 1

Resposta:

Explicação passo-a-passo:

A. 4x+4-4(x+1)=-3x+4  

=> 4x + 4 - 4x - 4 = - 3x + 4

=> 4x - 4x + 3x = 4 - 4 + 4

=> 3x = 4

=> x = 4/3

--------------------------------------------

2x/5-x/3=3  

=> (3(2x) - 5(x)) / 15 = 3

=> 6x - 5x = 15*3

=> x = 45

--------------------------------------------

5/6+1/7x=2

=> 1/7x = 2 - 5/6

=> 1/7x = (12 - 5)/6

=> 1/7x = 7/6

=> x = 7/6 * 7/1

=> x = 49/6

--------------------------------------------

9-3(x+3)=8-2(x+4)

=> 9 - 3x - 9 = 8 - 2x - 8

=> -3x = -2x

=> 3 is not equal to 2
