Question

1) RESOLVA AS EQUAÇÕES a)x-2=10 b) x-5=15 c)x-3=2 d) x+4=8 e)x+3=1 f)x+8=10 g)x+3=10 h)x-3=-1

Answer 1

Resposta:

$a)x - 2 = 10 \\ x = 10 + 2 \\ x = 12$

$b)x = 15 + 5 \\ x = 20$

$c)x = 2 + 3 \\ x = 5$

$d) x + 8 - 4 \\ x = 4$

$e)x = 1 - 3 \\ x = - 2$

$f) = x = 10 - 8 \\ x = 2$

$g)x = 10 - 3 \\ x = 7$

$h)x = - 1 + 3 \\ x = 2$
