Question

1-{[603-135: (6-12:X)]:4-144}:10=1 Multumesc!!!!

Answer 1

[(603 - 135:6 + 135:12:x ):4 -144]:10 = 1+ 1
(603:4 - 135:6 + 135:12:x):4:10 -144:10 = 2
Inmultim egalitatea cu 10:
(603:4 - 135:6 +135:12:x):4 -144 = 20
Inmultim cu 4:
603:4 - 135:4 + 135:12:x -144*4 = 20*4
135:12:x = 20*4 + 144*4 - 603:4 + 135 :4
135:12:x = 164*4 - 468:4 = 164*4 - 117
135/(12:x) = 164*4 -117
135*x/12 = 164*4 - 117
x = (164*4 -117)*12/135 = (656 - 117)*12/135 = 539*12/135 = 47,91
x = 47,91
