Question

resolvas as equaçoes d)2x-4-8=4x​

Answer 1

Resposta: x= -6

Explicação passo a passo:

2x - 4 - 8 = 4x

2x - 12 = 4x

2x - 4x = 12

-2x = 12

2x = -12

x= -12/2

x= -6

Answer 2

$\large\sf{}2x - 4 - 8 = 4x \\ \large\sf{}2x - 12 = 4x \\ \large\sf{}2x = 4x + 12 \\ \large\sf{}2x - 4x = 12 \\ \large\sf{} - 2x = 12 \\ \large\sf{} - 2x \div \left( - 2\right) = 12 \div \left( - 2\right) \\ \large\sf{}x = 12 \div \left( - 2\right) \\ \large\sf{}x = - 12 \div 2 \\ {\large\boxed{\boxed{  { \large \sf x = - 6}}}}$
