Answer 1

$a=3,\;b=2,\;c=4,\;d=5\\\\\\(234+124)a+237c=358a+237c=358\cdot3+237\cdot4=1074+948=2022\\\\562c+634c+76c=(562+634+76)c=1272c=1272\cdot4=5088\\\\569b+(69+77)d=569b+146d=569\cdot2+146\cdot5=1138+730=1868\\\\(645+567+867)c-659a=2079c-659a=2079\cdot4-659\cdot3=\\=8316-1977=6339$

Answer 2

It looks like you've provided a mathematical expression with various variables and equations. Let's break it down step by step:

1. Expression: (234 + 124)a + 237c
2. Expression: 562c + 634c + 76c
3. Expression: 569b
4. Expression: (69 + 77)d
5. Expression: (645 + 567 + 867)c
6. Expression: 659a
7. Equation: 3b = 2C = 4d = 5

Now let's simplify each expression and equation:

1. (234 + 124)a + 237c = 358a + 237c
2. 562c + 634c + 76c = 1272c
3. 569b
4. (69 + 77)d = 146d
5. (645 + 567 + 867)c = 2079c
6. 659a
7. Equations:
   • 3b = 2C
   • 4d = 5
