Answer:

x = 8

Step-by-step explanation:

Step 1: Subtract 5x from both sides.

  • [tex]7x-2-5x=5x+14-5x[/tex]
  • [tex]2x-2=14[/tex]  

Step 2: Add 2 to both sides.

  • [tex]2x-2+2=14+2[/tex]
  • [tex]2x=16[/tex]

Step 3: Divide both sides by 2.

  • [tex]2x/2=16/2[/tex]
  • [tex]x=8[/tex]

Step 4: Check if solution is correct.

  • [tex]7(8)-2=5(8)+14[/tex]
  • [tex]56-2=40+14[/tex]
  • [tex]54=54[/tex]

Therefore, x = 8.
