To solve this proportion, we can cross multiply.
(2x + 1)(15) = (3 - 7x)(5)
Expanding both sides:
30x + 15 = 15 - 35x
Combining like terms:
30x + 15 = -35x + 15
Add 35x to both sides:
65x + 15 = 15
Subtract 15 from both sides:
65x = 0
Divide by 65:
x = 0
Therefore, the value of x that satisfies the proportion 2x + 1:3 - 7x + 5:15 = x - 2:5 is x = 0.
