Question

If each blue square has a value of 1 and each red circle has a value x write an equation to represent the hanger.

Answer 1

On the left side we have 7 blue squares, and on the right side we have 2 red circles and 3 blue squares, therefore:

`\begin{gathered} 1+1+1+1+1+1+1=x+x+1+1+1 \\ add_{\text{ }}like_{\text{ }}terms\colon \\ 7=2x+3 \end{gathered}`
