Simplify the expression:

Question

7v+8–5–6v+8v–2

Answer 1

To simplify the expression $7v+8-5-6v+8v-2$, we can follow these steps:

1. Combine like terms for the variable $v$:

   • The terms with $v$ are: $7v-6v+8v$
   • Combining these: $$7v-6v+8v=(7-6+8)v=9v$$

2. Now, combine the constant terms:

   • The constant terms are: $8-5-2$
   • Combining these: $$8-5-2=1$$

3. Now combine the simplified $v$ terms and the constants: $$9v+1$$

Thus, the simplified expression is $\boxed{{\displaystyle 9v+1}}$.
