Question

Află pe x din . [x:3-7×(24+30÷5)]-23=27

Answer 1

(x:3-7•30)-23=27
x:3-210=50
x:3=260
x=3•260
x=520

Answer 2

[ x : 3 - 7 × ( 24 + 30 : 5 ) ] - 23 = 27

x : 3 - 7 × ( 24 + 6 )  = 27 + 23

x : 3 - 7 × 30 = 50

x : 3 - 210 = 50

x : 3 = 50 + 210

x : 3 = 260

x = 260 × 3

x = 780

Verific:

( 780 : 3 - 7 × 30 ) - 23 = ( 260 - 210 ) - 23 = 50 - 23 = 27
