Answer 1

Пошаговое объяснение:

(134545-х)+23=98. (х+52):7=700

134545-х+23=98. х+52=700* 7

-х= 98-134545-23. х=4980-52

-х=-134470. х=4848

х= 134470

2002+х*5= 46022.

5х= 46022-2002.

5х=44020

х=8804

34000+х*1000=76000

1000х=76000-34000

1000х=42000

х=42

Answer 2

Ответ:

$(134545 - x) + 23 = 98 \\ 134545 - x = 98 - 23 \\ 134545 -x = 75 \\ - x = 75 - 134545 \\ - x = - 134470 \\ x = - 134470 \div - 1 \\ x = 134470$

$2002 + x \times 5 = 46022 \\ 5x = 46022 - 2002 \\ 5x = 44020 \\ x = 44020 \div 5 \\ x = 8804$

$(x + 52) \div 7 = 700 \\ \frac{x + 52}{7} = \frac{700}{1} \\ x + 52 = 700 \times 7 \\ x + 52 = 4900 \\ x = 4900 - 52 \\ x = 4848$

$34000 + x \times 1000 = 76000 \\ 1000x = 76000 - 34000 \\ 1000x = 42000 \\ x = 42000 \div 1000 \\ x = 42$
