Question

RESOLVA AS EQUAÇOES 8(X+1) = 8 - 4 (2X-3)

Answer 1

8(x+1) = 8 - 4 (2x-3)  ⇒ propriedade distributiva
8x+8 = 8-8x +12
8x+8x = 12+8-8
16x = 12
x= 12/16
x = (12÷4)/(16÷4) ⇒ dividir numerador e denominador por 4
x = 3/4

Espero ter ajudado!

Answer 2

$\large\sf{}8\left(x + 1\right) = 8 - 4\left(2x - 3\right) \\ \large\sf{}8x + 8 = 8 - 4\left(2x - 3\right) \\ \large\sf{}8x + 8 = 8 - 8x + 12 \\\large\sf{}8x = - 8x + 12 \\ \large\sf{}8x + 8x = 12 \\ \large\sf{}16x = 12 \\ \large\sf{}16x \div 16 = 12 \div 16 \\ \large\sf{}x = 12 \div 16 \\ \large\sf{}x = \dfrac{12}{16} \\ \\ \large\sf{}x = \dfrac{12 \div 4}{16 \div 4} \\ \\ \large\sf{}x = \dfrac{3}{4} \\ \\ {\large\boxed{\boxed{  { \large \sf x = 0,75}}}}$
