Quizplus · Accepted Answer

Starting with the original equation:
$$7x+8y=8$$

We want to isolate the variable y. 
First, we can subtract 7x from both sides:
$$8y=-7x+8$$

Next, we can divide both sides by 8:
$$y=-\frac{7}{8}x+1$$

Therefore, the answer is D.

Solve 7x+8y=87 x + 8 y = 87x+8y=8 For Y A) 8y=−7x+88 y = - 7 x + 88y=−7x+8
