Question

Me confundí en la pasada, era 3(x-1)= 5x+4

Answer 1

3(x-1)=5x+4

3x-3=5x+4

3x-5x-3+4=0

-2x+1=0

1=2x

x=1/2

Answer 2

$3\left(x-1\right)=5x+4$

$\mathrm{Poner\:los\:parentesis\:utilizando}:\quad \:a\left(b-c\right)=ab-ac$

$3x-3=5x+4$

$3x-5x=4+3$

$-2x=7$

$\frac{-2x}{-2}=\frac{7}{-2}$

$x=-\frac{7}{2}\quad \left(\mathrm{Decimal:\quad }x=-3.5\right)$
