Question

resolva as equacoes a seguir: 3 (2x + 3) - 4 (x-1) = 3​

Answer 1

Explicação passo-a-passo:

$3(2x + 3) - 4(x - 1) = 3$

$6x + 9 - 4(x - 1) = 3$

$6x + 9 - 4x + 4 = 3$

$2x + 9 + 4 = 3$

$2x + 13 = 3$

$2x = 3 \times 13$

$2x = - 10$

$x = \frac{ - 10}{2}$

$\red{ \boxed{ \green{ \boxed{ \pink{ \boxed{x = - \: \: 5} }} } } }$

Answer 2

3 (2x+3)-4(x-1)=3
6x+9-4x+4=3
2x=3-9-4
2x=-10
x=-10/2
x=-5
