CHAPTER 8 / ESSENTIAL ALGEBRA I SKILLS 301
Concept Review 1: Solving Equations
- Explain the laws of equality.
- Are there any operations you can perform to both sides of an equation that will not yielda true equation?
Explain.
Show your steps and check your work in solving the following equations.
- 9x− 12 + 5 x= 3 x 4. (x−4)^2 = 5
5. 6.
Solve the following equations for the given expression by performing one operationon both sides.
- If , then 10x+ 12 = Operation: __ Solution: __
- If 18y+ 12 =7, then 6y+ 4 = Operation: __ Solution: __
