Describe on basic move you can use to transform the equation 3x - 17 = 20 into...

 a. 3x-37 = 0 

b. x - 17 = 20 -2x

What is a. subtract 20 from both sides

b. subtract 2x from both sides

4(2x + 7) + 2x - 3
What is 10x + 25
500

4x + 7 = 11x

What is: Subtract 4x from each side, then divide both sides by 7.

4x - 4x + 7 = 11x - 4x

7 = 7x

x = 1
