Question

tonya solved the literal equation 8x + 4y = 16 for y. which of the following could be her final answer? y = - 8x + 16 y = - 8x + 12 y = - 2x + 4 y = 2x - 4

Explanation:

Step1: Isolate the term with y

Starting with $8x + 4y=16$, subtract $8x$ from both sides: $4y=16 - 8x$.

Step2: Solve for y

Divide each term in $4y=16 - 8x$ by 4. We get $y=\frac{16}{4}-\frac{8x}{4}$, which simplifies to $y = - 2x+4$.

Answer:

$y=-2x + 4$
