Question

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

Answer 1

(456+112)-х=400
х=568-400
х=168

Answer 2

(456 + 112) - x = 400 X =168
x - (203 + 303 ) = 34 X = 540
( 283 - x) - 33 = 0 x = 250
