Final answer:
To subtract (3x + 5) from the sum of (6x + 8) and (9x + 10), first find the sum and then subtract (3x + 5) from it.
Step-by-step explanation:
To subtract (3x + 5) from the sum of (6x + 8) and (9x + 10), we first find the sum of (6x + 8) and (9x + 10):
(6x + 8) + (9x + 10) = 6x + 8 + 9x + 10
= 15x + 18
Next, we subtract (3x + 5) from the sum:
(15x + 18) - (3x + 5) = 15x + 18 - 3x - 5
= 12x + 13
Therefore, the result of subtracting (3x + 5) from the sum of (6x + 8) and (9x + 10) is 12x + 13.
