Question

Select ALL the equation that are equivalent to the equation below:

Answer 1

If we simplify the right side of the equation, we have:

$\begin{gathered} \frac{(4y+9)}{3}=1-(5y+8) \\ \frac{(4y+9)}{3}=1-5y-8 \\ \frac{(4y+9)}{3}=-5y-7 \end{gathered}$

Therefore option A (top left) is correct.

If we simplify the left side instead, we have:

$\begin{gathered} \frac{(4y+9)}{3}=1-(5y+8) \\ \frac{4}{3}y+3=1-(5y+8) \end{gathered}$

Therefore option D (bottom right) is correct.
