"Hello, welcome to do your homework. You see what - number should be subtracted from I inspire people to get is going to be one of the side and something should be subtracted from minus Pie by 2. So I will write as minus Phi by 2 L minus X. This is going to dissipate it redefined the this thing. Okay. Let's see how to find so as you can see here, I by 24 plus Phi by 12. It's going to be minus 6. Now as you can see here carefully, I'll multiple to year and a small pile too big to become like that sensor to become 21 denominator and 5 plus 10. It's going to be minus X. So the oil is going to be 15 by 20, but we want only want the smiles per gallon by 2020 we on the value of x will become less to become minus XL is going to be minus 1 by default.
