Final answer:
To solve the given equation, combine like terms on both sides by adding the fractions and constants separately. The simplified equation is 3/7x - 13.
Step-by-step explanation:
To solve the given equation, we need to combine like terms on both sides. So, we add the fractions (1/7x and 2/7x) and constants (-8 and -5) separately:
(1/7x - 8) + (2/7x - 5)
Combining the fractions gives us (3/7x), and combining the constants gives us (-13). Therefore, the simplified equation is:
3/7x - 13
So, the correct answer is (d) 3/7x - 13.
