If you want to represent the decimal solution as a fraction to match the format of an answer choice, just enter the variable and use the convert-to-fraction button on the left; this is one of the advantages regression has over graphing:
3
equals
4
Just to corroborate the results of the regression, you can also graph the equation and inspect the x-coordinates of the solution lines:
