Question

Tilda writes the equation 5y = 20x + 8. She wants to rewrite the equation in terms of x. After subtracting 8 from both sides of the equation, what number should she divide both sides of the equation by in order to accomplish this goal?

Answer 1

Starting from the equation given by Tilda:

\[ 5y = 20x + 8 \]

First, we subtract 8 from both sides:

\[ 5y - 8 = 20x \]

Next, to isolate \(x\), we need to divide both sides of the equation by 20. This will allow us to solve for \(x\):

\[ x = \frac{5y - 8}{20} \]

Thus, Tilda should divide both sides of the equation by **20** in order to rewrite the equation in terms of \(x\).
