Хз и вообщекакой это класс ?????

Answer 2

Let's solve each equation step by step:

1. $797 - y = 340 \times 2$ Start by multiplying 340 and 2: $797 - y = 680$ Now, isolate $y$ by subtracting 797 from both sides: $-y = -117$ Finally, multiply both sides by -1 to solve for $y$: $y = 117$

2. $160 + y = 310 \times 2$ Multiply 310 and 2: $160 + y = 620$ Now, isolate $y$ by subtracting 160 from both sides: $y = 460$

3. $192 - x = 440 \div 4$ Divide 440 by 4: $192 - x = 110$ Solve for $x$ by subtracting 192 from both sides: $-x = -82$ Multiply both sides by -1 to solve for $x$: $x = 82$

4. $x + 18 = 220 \div 2$ Divide 220 by 2: $x + 18 = 110$ Subtract 18 from both sides to solve for $x$: $x = 92$

So, the solutions are: $y = 117$ $x = 82$ $y = 460$ $x = 92$
