what equation does this set of algebra tiles represent?\ncombine like terms on each side of the equation. for example, write 3 instead of $1 + 1 + 1$.

Answer

Explanation:

Step1: Count the variable tiles on the left

There are 2 green tiles labeled $x$. $$2x$$

Step2: Count the unit tiles on the left

There are 7 yellow tiles labeled 1. $$7$$

Step3: Count the unit tiles on the right

There are 21 yellow tiles labeled 1 (arranged in a $3 \times 7$ grid). $$21$$

Step4: Formulate the final equation

Combine the terms from both sides using the equals sign. $$2x + 7 = 21$$

Answer:

2x + 7 = 21
