Question

Реши уравнения 50*х=500-150,у:90=36:12,1000-х=600-53

Answer 1

50 * х = 500 -150
50 * х =350
х = 350 : 50
х = 7
-------------------------------
50 * 7 = 500 - 150
   350 = 350

у : 90 = 36 : 12
у : 90 = 3
у = 3 * 90
у = 270
--------------------------------
270 : 90 = 36 : 12
           3 = 3

1000 - х = 600 - 53
1000 - х = 547
х = 1000 - 547
х = 453
----------------------------------
1000 - 453 = 600 - 53
            547 = 547

Answer 2

50х=350
х=350:50
х=7
50*7=350
350=350
у:90=3
у=90*3
у=270
270:90=36:12
3=3
1000-х=547
1000-547=х
х=453
1000-453=600-53
547=547
