Question

54-16÷{[36-6×4:(x-4×5)]÷5+2}=52

Answer 1

16:{[36-24:(x-20)]:5+2}=54-52
[36-24:(x-20)]:5+2=16:2
[36-24:(x-20)]:5=8-2
36-24:(x-20)=6x5
24:(x-20)=36-30
x-20=24:6
x=4+20
x=24

Answer 2

$54-16:{[36-6*4:(x-4*5)]:5+2}=52$
$16:{[36-24:(x-20)]:5+2}=54-52$
$[36-24:(x-20)]:5+2=16:2$
$[36-24:(x-20)]:5+2=8$
$[36-24:(x-20)]:5=8-2$
$[36-24:(x-20)]:5=6$
$36-24:(x-20)=6*5$
$36-24:(x-20)=30$
$24:(x-20)=36-30$
$24:(x-20)=6$
$x-20=24:6$
$x-20=4$
$x=20+4$
$\boxed{x=24}$
