The expression to simplify is
![5x-13+7y+26x](https://img.qammunity.org/2023/formulas/mathematics/high-school/jfc7acgarmxh5mj31qsd8c7gdfn2b4lua6.png)
We will simplify by combining like terms.
• There are FIVE x's and TWENTY-SIX more x's. We add.
5x + 26x = 31 x
• There is 1 constant, NEGATIVE THIRTEEN. No combining required so leave it as is.
,
•
,
• There is 1 term with y, which is SEVEN y. No combining required, so we leave it as is.
The final expression is
![\begin{gathered} 5x-13+7y+26x \\ =31x+7y-13 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/high-school/75dllj7qc114rbo0yb6x0uxs2c84m9f0yr.png)
