The answer is:
Below
Work/explanation:
An expression is a term (or a few terms) put together with plus or minus signs.
Examples of expressions are:
![\sf{3x+2}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/inhkt0whjttlxyk96xnwmr4tvux6bwxbtd.png)
![\sf{4x-7}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/ymgh7q4hrshzqkcecpcs1d4ga5eh51jwbj.png)
![\sf{p+12}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/b3tv3bsvxnur13j5chspi0euwaqe9x09bq.png)
An equation is two expressions put together with a = sign, which shows that they're equal.
Examples of equations are:
![\sf{3x=12}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/9ranlazj5za7plzlelath1njbazqj4soij.png)
![\sf{4x-7=15}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/nrbi53z3pjayw5hzks10abl4d6qy7b0i65.png)
![\sf{p+12=24}](https://img.qammunity.org/2019/formulas/mathematics/middle-school/fvohyidiij1ha2iuz90igyikc3ahv6m9vq.png)
Hence, this is the difference between an equation and an expression. Do not use these terms interchangeably.
