Question

How do you solve `175= - 7( - 1+ 3v )`?

Answer 1

`v=-8`

Explanation:

`175=-7(-1+3v)`
Let start by distributing the right side
`175 = (-7)(-1)+(-7)(3v)`
`175 = 7 - 21v`
We always want to make sure we put the variable we are solving in front(leading the equation). For that, we Flip the equation
`-21v + 7 = 175`
Group the common term
`21v = 175 - 7`
`21v = 168`
Finally, divide both sides by `color(red)(-21)`
`(-21v)/color(red)(-21) = 168/color(red)(-21)`
`v= -8`
