Question

resolva a equacao:
a)2x+1=x1 b)14x-70=10-6x

d)x-1=3x+11 e)3x+6=2x+10

Answer 1

Resposta:

$a)2x+1=x1$

$2x-x=1-1$

$x=0$

$b)14x-70=10-6x$

$14x+6x=70+10$

$20x=80$

$x=80/20$

$x=4$

$d)x-1=3x+11$

$x-3x=11+1$

$-2x=12$

$x=12/-2$

$x=-6$

$e)3x+6=2x+10$

$3x-2x=10-6$

$1x=4$

$x=4/1$

$x=4$
