Answer:
All real numbers
Step-by-step explanation:
We can first factor the negative onto the parentheses to get [tex]-v-4+5=4v+1-5v[/tex]. Now we can combine like terms, getting [tex]-v+1=-v+1[/tex] . Since both sides are equal, the answer is "all real numbers," which can be represented with this symbol: [tex]\mathbb{R}[/tex]. (an R but with an extra vertical line in front)
