Question

Реши уравнения х+350=618
х-350=618
х×50=400
х÷50=400
520-х=26
520÷х=26

Answer 1

х+350=618, х=618-350, х=268

х-350=618, х=618+350, х=968

х*50=400, х=400:50, х=8

х:50=400, х=400*50, х=20 000

520-х=26, х=520-26, х=494

520:х=26, х=520:26, х=20

Answer 2

1) х-350=618
Х=968
2)x*50=400
x=400/50
x=8
3)x/50=400
x=400*50
x=20000
4)520-x=26
X=520-26
X=494
5)520/x=26
X=20
