Question

Реши уравнения 50*х=725+275
200:у=200:4
х*2*4=96
с:6=148-58
792-а=112*4
у*3*5=90

Answer 1

50x = 1000
x = 1000/50
x = 20

200y = 200 × 4
200y = 800
y =800/200
y = 4

8x = 96
x = 96/8
x = 12

c/6 = 90
c = 90 × 6
x = 540

792 - a = 448
- a = 448 - 792
- a =- 344
a = 344

15y = 90
y = 90/15
y = 6

Answer 2

200:4=50
200:50=4
200:4=200:4
