Answer 2

Let's solve the given equations step by step.

1. $-257 = 104243 - (x + 77)$: $x + 77 = 104243 + 257$ $x + 77 = 104500$ $x = 104500 - 77$ $x = 104423$

2. $1151347 - (x - 347) = 794$: $1151347 - x + 347 = 794$ $1151347 + 347 = 794 + x$ $1151694 = 794 + x$ $x = 1151694 - 794$ $x = 1150900$

3. $794(644 - x) \times 38 = 11704$: $794(644 - x) = \frac{11704}{38}$ $644 - x = \frac{11704}{38 \times 794}$ $644 - x \approx 0.386$ (approximately)

   Solving for $x$: $x \approx 644 - 0.386$ $x \approx 643.614$

4. $(x + 119) \div 17 = 28$: $x + 119 = 17 \times 28$ $x + 119 = 476$ $x = 476 - 119$ $x = 357$

The solutions for the given equations are:

• $x = 104423$
• $x = 1150900$
• $x \approx 643.614$
• $x = 357$
