1st box = Putting all variables and constants on opposite sides by subtracting 4 from both sides

2nd box = Combine like terms

3rd box = Isolating the x further by subtracting 8 from both sides

4th box = Dividing 3 from both sides to make the coefficient equal to 1

5th box = Answer of x

Step-by-step explanation:

These are the steps to solving a linear equation. I think this is what your question is asking, but I'm not completely sure. Hope this helps :)

1. Given

2. Subtraction property of equality

3. Substitution

4. Addition property of equality

5. substitution

6. Division property of equality

Step-by-step explanation:

For #2, your subtracting 4x from both sides of the equation to balance off both sides.

#3 is the result of #2

#4; your adding 8 to both sides

#5. the result of #4

#6 you divided 3x by 3 to get x alone and then divided 21 by 7 to get you final answer

Hope this helps you!
