Реши уравнения.
(134 545 - x) + 23 = 98
2002 + x 5 = 46 022
(х + 52) :7= 700
34 000 + x 1000 = 76 000​

Answer 1

Ответ:

1) (134 545 -x)+ 23=98

134 545-x=98-23

134 545-x=75

x=75-134 545

x=134 470.

2) 2002 + x*5 = 46 022

5x = 46 022 - 2002

5x = 44 020

x = 44 020:5

x = 8804.

3) (x + 52) :7= 700

x+52 = 700*7

x+52= 4900

x= 4900-52

x= 4848.

4) 34 000 +x*1000 = 76 000

1000x= 76 000 - 34 000

1000x = 42 000

x = 42 000 : 1000

x = 42.
