Найти х в уравнении. (456 + 112) - x = 400 x - (203 + 303) = 34 (283 - x) - 33 = 0 382 - (x + 42) = 111 (536 + x) - 420 = 116 437 - (227 + x) = 0 468 - 217 - x = 51
( 536 + x )- 420 = 116 x =
x = 0
(456 + 112) - x = 400 X =168 x - (203 + 303 ) = 34 X = 540 ( 283 - x) - 33 = 0 x = 250
(456+112)-х=400 х=568-400 х=168
