Hi

Example A: 2n + 3 = 13  |two-step 

Example B: n + 3 = 13   |one-step (subtracting 3 from both sides) n = 10

Likeness: both involve isolating the variable on one side of the equation

Difference: A second step is necessary in the two-step to accomplish this.

for example:

2n + 3 = 13 

  2n = 10  |Step one, subtracting 3 from both sides

   n = 5   |Step two, dividing both sides by 2
