Question

Resolva

(x+5)/2 + 5 - 4 = 30

Answer 1

$\frac{x+5}{2} +5 - 4 = 30$
$(+4 -5) \frac{x+5}{2} +5 - 4 = 30 (+4 -5)$
$(.2) \frac{x+5}{2} = 29 (.2)$
$(-5)x+5= 58 (-5)$
$x=53$

Answer 2

(x + 5) = 30
2+5-4

(x + 5)  = 30
    3
x + 5 = 3* 30
x + 5 = 90
x = 90 -5
x = 85
ou
x + 5 + 5 - 4 = 30
    2
x + 5 + 1 = 30
   2
x + 5 +2 = 60
x + 7 = 60
x = 60 - 7
x = 53
