Question

235-{16*100/[36-42/x/(15/3-4/1)-20]+14*5}=5 Va rog sa ma ajutati !!!!!!!!!!!!

Answer 1

235-{16·100:[36-42:x:(15:3-4:1)-20]+14·5}=5
1600:[36-42:x:(5-4)-20]+70=235-5
1600:[36-42:x:1-20]+70=230
1600:[36-42:x:1-20]+70=230-70
1600:[36-42:x:1-20]=160
36-42:x:1-20=1600:160
36-42:x:1-20=10
36-42:x:1=10+20
36-42:x:1=30
42:x:1=36-30
42:x:1=6
x:1=42:6
x:1=7
x=7·1
x=7
