Question

) Resolva as equações:
a) |x - 41 = -7
b) x? - 9 = 0
c) |2x - 8) = 6
d) (3x - 41 = 2x + 6

Answer 1

$a)x - 41 = - 7 \\ x = - 7 + 41 \\ x = 34$

$b)x - 9 = 0 \\ x = 9$

$c)2x - 8 = 6 \\ 2x = 6 + 8 \\ 2x = 14 \\ x = \frac{14}{2} \\ x = 7$

$d)3x - 41 = 2x + 6 \\ 3x - 2x = 6 + 41 \\ x = 47$
