Question

184+(×+65)=292. (175+×)-137=108. (×+624)-276=357. 69+(87-×)=103.

Answer 1

1.

184+(x+65)=292

184+x+65=292

249+x=292

x=292-249

x=43

Answer 2

Пошаговое объяснение:

1) 184+(x+65)=292

184+x+65=292

249+x = 292

x=292-249

x= 43

2)(175+x)-137=108

175+x-137 = 108

38+x = 108

x = 108-38

x= 70

3)(x+624)-276=357

x + 624 - 276 = 357

x + 348 = 357

x=357-348

x = 9

4)69+(87-x)=103

69 +87 - x =103

156 - x = 103

- x = 103 - 156

-x = - 53

x = 53
