Question

(2) 4y + 20 = 5x

Explanation:

Step1: Solve for y

Start with the equation \(4y + 20 = 5x\). Subtract 20 from both sides: \(4y = 5x - 20\).

Step2: Divide by 4

Divide each term by 4: \(y=\frac{5}{4}x - 5\). If solving for x: from \(4y + 20 = 5x\), divide by 5: \(x=\frac{4y + 20}{5}=\frac{4}{5}y + 4\).

Answer:

If solving for \(y\): \(y = \frac{5}{4}x - 5\); If solving for \(x\): \(x=\frac{4}{5}y + 4\)
