Hey there!


  • \bold{2(x+10)=x+23}
  • Firstly, you have to distribute

  • \bold{2(x+10)}

  • \bold{2(x)=2x}

  • \bold{2(10)=20}

  • \bold{2x+20=x+23}
  • Now, let's do the opposite of
    \bold{addition} which is
    \bold{subtraction}, so we have to SUBTRACT by
    \bold{20} on each of your sides

  • \bold{2x+20-20=x+23-20}

  • \bold{Cancel:20-20}

  • \bold{Keep:2x=x+3}

  • \bold{Simplify} it
    \uparrow
  • SUBTRACT by the
    \bold{x} value on each of your sides

  • \bold{2x-x=x+3-x}

  • \bold{Simplify} that as well
    \uparrow

  • \boxed{\boxed{\bold{Answer:x=3}}}\checkmark

Good luck on your assignment and enjoy your day!
