Answer:

x = 15

Step-by-step explanation:

Step 1: Set up the equation.

  • [tex]3x + 18 + 6x - 16 + 43 = 180[/tex]

Step 2: Simplify both sides of the equation.

  • [tex](3x+6x)+(18-16+43)=180[/tex]
  • [tex]9x + 45 = 180[/tex]

Step 3: Subtract 45 from both sides.

  • [tex]9x + 45 - 45 = 180 - 45[/tex]
  • [tex]9x = 136[/tex]

Step 4: Divide both sides by 9.

  • [tex]\frac{9x}{9} = \frac{135}{9}[/tex]
  • [tex]x = 15[/tex]
