Question

What answers go in the boxes?

Answer 1

1. The first box is given since the program is restating the equation.
2. The second box is addition property of equality since the equation is simplified after the 2x was added on both sides of the equation.
3. The third box is division property of equality since 3 = x is the result of 18/6.

Answer 2

Given, Addition Property of Equality, and Division Property of Equality

Explanation:

Given 18-2x=4x,

You use the addition property of equality and add 2x to each side to get 18=6x,

and you use the division property of equality and divide each side by 6 to get 3=x.
