Question 189951
Q:  2x + 10 > -4 – x 

working:
2x + x > -4 - 10
3x > -14
ans: -14/3

am i right??

YES you are absolutely right till the 2nd step :)
after that the answer would be x > -14/3, which means all the values of x that are greater than -14/3. This would include the domain of x as (-14/3 , infinity)

Best of Luck !
