When you have 2x plus 2x, you are essentially adding two terms that have the same variable, which is x in this case. This simplifies to 4x, because you are combining the coefficients (2 + 2) while keeping the variable x the same. So, 2x plus 2x equals 4x.
Oh honey, it's simple math. 2x plus 2x is just 4x. You're basically adding two groups of 2x together to get 4x. Easy peasy lemon squeezy!
