MULTIPLE CHOICE QUESTION

15 mins • 1 pt

Kiran says that a solution to the equation  x+4=20 x+4=20\  must also be a solution to the equation  5(x+4)=1005\left(x+4\right)=100  .  Select the most convincing reason why this is true.

It just is.

If you multiply both sides of  x+4=20x+4=20  by 5, you get  5(x+4)=1005\left(x+4\right)=100  .

Because  5x+4=1005x+4=100  .

The equations are just equivalent.
