Question

448 = -5v + 8(-5 - 7v)
What is v?

Answer 1

Answer:

v = -8

Step-by-step explanation:

First we would have to distribute the 8(-5 - 7v). To do this we would multiply 8 by -5 and 8 by -7v to get $448=-5v-40-56v$. After this, we would have to simplify like terms by subtracting 56v from -5v to get $448=-61v-40$. We now have to get the variable on one side and to do that, we can add 40 to both sides to get $488=-61v$. Finally to get the variable alone, we would have to divide both sides by -61 to get $v=-8$.

Answer 2

Step-by-step explanation:

448 = - 5 v - 40 - 56 v

448 + 40 = - 61 v

488 = - 61 v

v = - 8
