A student solved the equation x+2(x+1)=17 below and showed their work in the table below.

Answer 1

Equation solved by a student has been given as,

$x+2(x+1)=17$

Solution in each step,

Step 1 → $x+2x+2=17$

Step 2 → $3x+2=17$

Step 3 → $3x=15$

Step 4 → $x=5$

In step 2, addition of two terms have been done → $(x+2x=3x)$

        Therefore, property used to reach at step 2 → Addition property of equality
