Solve for x. 7(3 - x) = 8(4 - 2x)
a. x = -53/23
b. x = -5/9
c. x = 11/23
d. x = 11/9

7(3-x) = 8(4-2x)

21-7x = 32-16x

16x-7x = 32-21

9x = 11

x = 11/9

SO, OPTION D IS YOUR ANSWER.

answer: domain and range mean all possible values of x and y that could be substituted to the inequality. a solution means all possible values that make the inequality statement true. so while the range is still all real numbers, the solution is the shaded area, for which y will always be greater than the line of the function.
