Question

I need help with this V-4=v+2+7v-42 ??

Answer 1

`\boxed{\bold{v \ = \ (36)/(7)}}`

Explanation:

Subtract v from both sides

`\bold{v-4-v=v+2+7v-42-v}`

Simplify

`\bold{-4=2+7v-42}`

Switch sides

`\bold{2+7v-42=-4}`

Group like terms

`\bold{7v+2-42=-4}`

Subtract the numbers: 2 - 42 = -40

`\bold{7v-40=-4}`

Add 40 to both sides

`\bold{7v-40+40=-4+40}`

Simplify

`\bold{7v=36}`

Divide both sides by 7

`\bold{(7v)/(7)=(36)/(7)}`

Simplify

`\bold{v=(36)/(7)}`
