Answer 1

(234+124)а+237с

358а+237с

358×3+237×4=2022

==================

562с+ 634с+76с

=5088

==================

569b+(69+77)d

569b+146d

Answer 2

Evaluating Expressions with Multiple Variables

To evaluate the given expression with multiple variables, we need to substitute the given values for the variables and perform the necessary calculations. Let's break down the expression and evaluate it step by step.

The given expression is:

(234 + 124) * a + 237 * 562 * c + 634 * 76 * c + 569 * b + (69 + 77) * d * (645 + 567 + 867) - 659 * a * a + 3 * b + 2 * d + 5 * c + 4

Now, let's substitute the given values for the variables:

a = 3 b = 2 d = 5 c = 4

Substituting these values into the expression, we get:

(234 + 124) * 3 + 237 * 562 * 4 + 634 * 76 * 4 + 569 * 2 + (69 + 77) * 5 * (645 + 567 + 867) - 659 * 3 * 3 + 3 * 2 + 2 * 5 + 5 * 4 + 4

Simplifying the expression further:

(358) * 3 + 237 * 562 * 4 + 634 * 76 * 4 + 569 * 2 + (146) * 5 * (2079) - 659 * 3 * 3 + 3 * 2 + 2 * 5 + 5 * 4 + 4

Calculating the values:

1074 + 532248 + 193472 + 1138 + 730 * 2079 - 659 * 9 + 6 + 10 + 20 + 20 + 4

Simplifying the expression:

1074 + 532248 + 193472 + 1138 + 1513170 - 5931 + 6 + 10 + 20 + 20 + 4

Calculating the values:

8785611

Therefore, when the values of the variables are a = 3, b = 2, d = 5, and c = 4, the given expression evaluates to 8785611.
