Answer:

v = -14

Step-by-step explanation:

» Solution

Step 1: Distribute the -4 to the terms inside the parantheses.

  • [tex](-4)(7)+(-4)(v)=28[/tex]
  • [tex]-28-4v=28[/tex]  
  • [tex]-4v-28=28[/tex]

Step 2: Add 28 to both sides.

  • [tex]-4v-28+28=28+28[/tex]
  • [tex]-4v=56[/tex]

Step 3: Divide both sides by -4.

  • [tex]-4v/-4=56/-4[/tex]
  • [tex]v=-14[/tex]

Therefore, v = -14.
