Question

Doubling x and adding 3 is the same as tripling x and adding 1

Answer 1

If x was tripled, then it would indeed be 3x. The answer wouldn't be x^3 because x isn't being multiplied by itself three times in a row. Whenever value is tripled, it's multiplied by three, but not the power of 3.

Answer 2

2x + 3 = 3x + 1

x = 2

hope that helps ✌
