=35x7-4x(89-(300-84)÷3)=

=35x7-4x(89-216÷3)

=35x7-4x(89-72)

=35x7-4x17

=245-68=177

(220-(2xX-227)+13)÷20=1001-996

(220-(2xX-227 )+13)÷20=5

(220-(2xX-227) +13l0=20x5

(220-(2xX-227) +13)=100

(2xX-227)+13=220+100

(2xX-227) +13=320

(2xX-227) =320-13

(2xX-227) =307

2xX=307+227

2xX=534

X=534÷2

X=267

Sper ca te am ajutat
