Answer:

A). X = -3

Step-by-step explanation:

Step 1: Add 20 to both sides.

  • [tex]7x-20+20=-41+20[/tex]
  • [tex]7x=-21[/tex]

Step 2: Divide both sides by 7.

  • [tex]7x/7 = -21/7\\[/tex]
  • [tex]x=-3[/tex]

Step 3: Check if solution is correct.

  • [tex]7(-3)-20=-41[/tex]
  • [tex]-21-20=-41[/tex]
  • [tex]-41=-41[/tex]
