Asked by Isabella

An equation is modeled below using algebra tiles. Which value of x makes the equation true?

A. x = 7 C. x = 13
B. x = -7 D. x = -13

The algebra tiles:
There is a large block with an "x." Next to it are 3 small blocks with "1" inside of it. Then there is an equal sign. Then there are 10 blocks with "1" inside of it again.

Can someone help me?

If the x is equal to the smaller blocks, then just count the smaller blocks. There are 3 small blocks, and then there are 10 small blocks. 10+3=13. SO it would look like x=10+3, or x=13. I hope that helped.
