Question 1130782
Solve the systems of equations by using the substitution method. (If the system is dependent, enter a general solution in terms of c.
{18x− 12y=24
   −6x+ 4y= 12
<pre>18x - 12y = 24 ------ eq (i)
- 6x + 4y = 12 ------ eq (ii)
- 18x + 12y = 36 ------- Multiplying eq (ii) by 3 ------ eq (iii)
0 = 60 ------- Adding eqs (iii) & (i)
From above, {{{0 <> 60}}}, so what do you think? 
At least 40 of these have been done for you in the past few days.
You still can't do these on your own?
I really hope that no-one will do any more for you! It's getting awfully boring and annoying doing so many of these for you!
