Karissa begins to solve the equation startfraction one-half endfraction left-parenthesis x minus 14 right-parenthesis plus 11 equals startfraction one-half endfraction x minus left-parenthesis x minus 4 right-parenthesis.. her work is correct and is shown below.

three lines of math. the first line, startfraction one-half endfraction left-parenthesis x minus 14 right-parenthesis plus 11 equals startfraction one-half endfraction x minus left-parenthesis x minus 4 right-parenthesis. the second line, startfraction one-half endfraction x minus 7 plus 11 equals startfraction one-half endfraction x minus x plus 4. the third line startfraction one-half endfraction x plus 4 equals negative startfraction one-half endfraction x plus 4.
startfraction one-half endfraction x minus 7 plus 11 equals startfraction one-half endfraction x minus x plus 4.
startfraction one-half endfraction x plus 4 equals negative startfraction one-half endfraction x plus 4.
when she subtracts 4 from both sides, startfraction one-half endfraction x equals negative startfraction one-half endfraction x. results. what is the value of ?
