Question

Resolva (x-1)-(x+2)+2(x-3)-5=0

Answer 1

Resposta:

O valor de "x" é: 7

Explicação passo-a-passo:

●Equação linear.

$\mathtt{(x-1)-(x+2)+2(x-3)-5=0}$

$\mathtt{x-1-x-2+2x-6-5=0}$

$\mathtt{\cancel{x}-1\cancel{-x}-2+2x-6-5=0}$

$\mathtt{+2x-14=0}$

$\mathtt{2x=14}$

$\mathtt{x=\dfrac{14}{2}}$

$\mathtt{\colorbox{blue}{x=7}}$
