Question

6(2x+1)=90-2x gente por favor me ajudem

Answer 1

Aplica a distributiva
6.2x + 6.1 = 90-2x
12x + 6 = 90-2x
Junta os semelhantes
12x+2x = 90-6
14x = 84
84÷14 = x
X = 6

Answer 2

$6(2x + 1) = 90 - 2x \\ 12x + 6 = 90 - 2x \\ 12x + 2x = 90 - 6 \\ 14x = 84 \\ x = \frac{84}{14} \\ x = 6$

Ou seja, x será igual a 6.
