(07.02 mc)

an equation is shown below:

3(2x − 7) = 3

part a: how many solutions does this equation have?

part b: what are the solutions to this equation? show your work.

Part A:

1 solution. It is a linear equation => one solution.

Part B:

                                        3(2x - 7) = 3

(divide through by 3)         2x - 7 = 1

(add 7 to both sides)               2x = 8

(divide through by 2)                 x = 4
