Question

Solve the equation 3x + 5y = 15 for y

A. y = 3(15 - 3x)
B. y = 5/3x - 3
C. y = 15 - 3x
D. y = 3 - 3/5x

Answer 1

To solve the equation 3x + 5y = 15 for y, isolate y by subtracting 3x from both sides and then dividing by 5. The correct answer choice is option A.

Step-by-step explanation:

To solve the equation 3x + 5y = 15 for y, we need to isolate y on one side of the equation. Here are the steps:

1. Subtract 3x from both sides of the equation: 5y = 15 - 3x
2. Divide both sides of the equation by 5: y = (15 - 3x) / 5

The answer is y = (15 - 3x) / 5. Therefore, option A is the correct answer choice.
