Question

m6|l3 reasoning about contexts with strip diagrams (part 2)
write a second equation to represent the diagram.
diagram with 6, y, y, y boxes summing to 30
30 = 6 + y + y + y
□ = □ + □
tiles: 30, 3y, 6y, 3, 6

Explanation:

Step1: Simplify like terms

The original equation is $30 = 6 + y + y + y$. Combine the $y$ terms: $y+y+y=3y$, so the equation becomes $30 = 6 + 3y$.

Step2: Rearrange the equation

Rewrite the equation to match the required format $\square = \square + \square$ by keeping the left and right sides in the correct order, or reordering to show the combined variable term clearly. The simplified rearranged form is $30 = 3y + 6$.

Answer:

$30 = 3y + 6$
