Question

An equation is shown below: 3(2x − 7) = 9

Part A: How many solutions does this equation have?

Part B: What are the solutions to this equation? Show your work.

Answer 1

1 solution

Explanation:

3(2x-7)=9

dustribute: (3)(2)+(3)(-7x)=9

6+-21x=9

subtract 6 from both sides: -21x=3

Divide both sides by -21: x=-1/7

so your 1 solution is x = - 1/7
