Question

Explain how you would use algebra tiles to solve x - 3 = 7

Answer 1

Answer:

Start by laying out 7 tiles, and then adding 3. Whatever that number of tiles is equals x.

x = 10

10 - 3 = 7

Answer 2

Answer: x=10
explanation: switch subtraction to addition to both sides and add 3 to both sides making it 7 + 3 witch equals 10
