Question

V/8 - 3.1 = -15.9 solve for v

Answer 1

v = -102.4
Hope this helped

Answer 2

`(v)/(8) -3.1=-15.9`

Simplify equation:

`(1)/(8)v+-3.1=-15.9`

`(1)/(8) v-3.1=-15.9`

Add 3.1 to both sides:

`(1)/(8) v-3.1+3.1=-15.9+3.1\\`

`(1)/(8) v=-12.8`

Multiply both sides by 8:

`8*((1)/(8) v)=(8)*(-12.8)\\-102.4`

`\fbox{v=-102.4}`
