Final answer:
To solve the equation 7x+8y=3 for y, subtract 7x from both sides and then divide by 8.
Step-by-step explanation:
To solve the equation 7x+8y=3 for y, we need to isolate the variable y on one side of the equation. We can start by subtracting 7x from both sides:
7x + 8y - 7x = 3 - 7x
Simplifying, we get:
8y = 3 - 7x
Now, we can divide both sides of the equation by 8 to solve for y:
y = (3 - 7x)/8
Therefore, y equals (3 - 7x)/8.
