Question

5) 103 – ( 81 – ( 49 + c)) = 58.

Answer 1

Пошаговое объяснение:

103 - (81 - (49 + с)) = 58

(81 - (49 +с))= 103-58

(81 - (49 +с))= 45

(49+с))= 81-45

(49+с))= 36

с=36-49

с=     -13

Ответ: с= -13

Answer 2

Let's solve the equation step by step:

1. Start with the innermost parentheses: (49 + c)
2. Perform the addition: 49 + c
3. Now, the equation becomes: 103 – (81 – (49 + c)) = 58.
4. Move to the next set of parentheses: (81 – (49 + c))
5. Perform the addition within the parentheses: 81 - (49 + c) = 81 - 49 - c = 32 - c
6. Now, the equation becomes: 103 – (32 - c) = 58.
7. Proceed with the remaining subtraction: 103 - (32 - c) = 103 - 32 + c = 71 + c
8. Now, the equation becomes: 71 + c = 58.
9. Finally, solve for 'c': c = 58 - 71 = -13.

Therefore, the value of 'c' that satisfies the equation is -13.
