Question 1

1.

2x+3=6x+9

Step 1: Use inverse operations to move your variables to the right side.
Step 2: Use inverse opperations(opposites) to move the 9 to the left side
Step 3: Divide both sides by the number connected to your variable to find your answer

Question 2

2.

3x+9=3x+10

Step 1: Use inverse operations to move your variables to the left side
Step 2: if all of your variables drop out, if the equations is true (4=4, 9=9) there are infinitely many solutions, if the remaining equation is false, there are no solutions.

Question 3

3.

-9x+9=-9x+9

Step 1: Use inverse operations to move your variables to the left side
Step 2: if all of your variables drop out, if the remaining equation is true (4=4, 9=9) there are infinitely many solutions, if the remaining equation is false, there are no solutions.

Question 4

4.

2x+10=2(x+2)

Step 1: Distribute (multiply) the number outside the parenthesis to the variable and number inside.
Step 2: rewrite your equation now that you've simplified the right side
Step 3: Use inverse operations to move your variables to the left side
Step 4: if all of your variables drop out, if the remaining equation is true (4=4, 9=9) there are infinitely many solutions, if the remaining equation is false, there are no solutions.
