Question

X- 7 +2 (X-4)= -3 ( X-2) -8

Answer 1

$X-7+2\left(X-4\right)=-3\left(X-2\right)-8\quad :\quad X=\frac{13}{6}\quad \left(\mathrm{Decimal}:\quad X=2.16666\dots \right)$

$\mathrm{Dividir\:ambos\:os\:lados\:por\:}6$

$\frac{6X}{6}=\frac{13}{6}$

$X=\frac{13}{6}$

$\mathrm{Adicionar\:}3X\mathrm{\:a\:ambos\:os\:lados}$

$3X+3X=-3X+13+3X$

$6X=13$
