Afla cat e x? x-(642-284)=607,x-(159+266)=340,x+(800-647)=729,x-(654-290)=56

Answer 1

Răspuns

x - ( 642 - 284 ) = 607

x - 358 = 607

x = 607 + 358

x = 965

_________________

x - ( 159 + 266 ) = 340

x - 425 = 340

x = 340 + 425

x = 765

_________________

x + ( 800 - 647 ) = 729

x + 153 = 729

x = 729 - 153

x = 576

____________________

x - ( 654 - 290 ) = 56

x - 364 = 56

x = 56 + 364

x = 420
