In this step, we are subtracting 13 from both sides of the equation. This is done in order to isolate the variable term, 2x, on one side of the equation. By subtracting 13 from both sides, we cancel out the +13 and -13 on the left side of the equation, leaving us with 2x on the left side. On the right side, we have 17 - 13, which equals 4. Therefore, the equation simplifies to 2x = 4.
Step 5: 2x+13−13=17−13
