What is the solution to ... 12x-7

There is no solution to that line because there is only one line which therefore cannot contain any solutions.

Step-by-step explanation:

12x-7 is only one line if there is two lines then there can be a solution because if the line meets in one location then that place where they meet is the solution.

2 x - 7 = 7 2x-7=7 2x-7=7. Add 7 to both sides. Simplify 7 + 7 7+7 7+7 to 1 4 14 14. Divide both sides by 2.
