Решение:
5(c+3) ÷ 6 = 8(10-c) ÷ 6
5c + 15 ÷ 6 = 80 - 8c ÷ 6
Multiplying both sides of the equation by 6 to eliminate the fractions:
5c + 15 = 48 - 8c
Adding 8c to both sides:
13c + 15 = 48
Subtracting 15 from both sides:
13c = 33
Dividing both sides by 13:
c = 33/13c = 2.54 (rounded to two decimal places)
Therefore, the solution to the equation is c = 2.54.
