Answer:
See explanation.
Step-by-step explanation:
An expression is a <u>set of terms that are combined using addition, subtraction, multiplication, or division.</u> The following are examples of expressions:
![2x-1](https://tex.z-dn.net/?f=2x-1)
![5y+8](https://tex.z-dn.net/?f=5y%2B8)
![2](https://tex.z-dn.net/?f=2)
Note: expressions do not equal anything.
In contrast, equations are <u>expressions that equal at least one term.</u> The following are examples of equations:
![2y-4=26](https://tex.z-dn.net/?f=2y-4%3D26)
![4x-4=0](https://tex.z-dn.net/?f=4x-4%3D0)
![x=10](https://tex.z-dn.net/?f=x%3D10)
![y=x+2](https://tex.z-dn.net/?f=y%3Dx%2B2)
Note: equations <u>do</u> equal a term, as shown in the examples.
