Question

QUAL A RESPOSTA CERTA PRA ESSA EQUACAO 2+X=3, 1+3X+X2=0, X+1=3+5X, X(+1)=4, X+3X-2=6X

Answer 1

Explicação passo-a-passo:

$2 + x = 3 \Longrightarrow x = 3 - 2 = 1.\\1 + 3x + x + 2 = 0 \Longrightarrow 4x + 3 = 0 \Longrightarrow 4x = -3 \therefore x = \dfrac{-3}{4}\\x + 1 = 3 + 5x \Longrightarrow 1 - 3 = 5x - x \Longrightarrow -2 = 4x \therefore x = -\dfrac{1}{2}\\x(+1) = 4 \therefore x = \dfrac{4}{1} = 4\\x + 3x - 2 = 6x \Longrightarrow 4x - 6x = 2 \Longrightarrow -2x = 2 \therefore x = -\dfrac{2}{2} = -1.$
