Question

Encontre o valor do x das equações abaixo

Answer 1

a) $x+10=-13$
$x=-13-10$
$x=-23$

b) $2x+10=14$
$2x=14-10$
$2x=4$
$x=2$

c) $x+2x=10$
$3x=10$
$x= \frac{10}{3}$

d) $2x+10=x-10$
$2x-x=-10-10$
$x=-20$

e) $2x- \frac{1}{3} =10$
$6x- 1=30$
$6x=31$
$x= \frac{31}{6}$

f) $x+ \frac{1}{3} = \frac{2}{3}$
$3x+ 1= 2$
$3x=1$
$x= \frac{1}{3}$

g) $3x+10=19$
$3x=19-10$
$3x=9$
$x=3$
