Question

Реши уравнения:
(14-x)*50=300, y:9+48=60, 72-56:z=64

Answer 1

1) 700-50X=300
-50X=-400
X=400/50
X=8
2)Y/8=12
Y=8*12
Y=96
3)-56/Z=-8
Z=56/8
Z=7

Answer 2

1) (14-х)* 50 = 300
700 - 50х = 300
-50х=300-700
-50х= -400
х = -400 : (-50)
х = 8

2) y:9+48=60
у:9 = 60 - 48
у:9 = 12
у = 12*9
у = 108

3) 72-56:z=64
-56:z=64-72
-56:z= -8
Z = 56:8
z = 7
