I'm assuming you mean: 14a - 93 = 49 - 57a If so then the answer is something like this... 14a + 57a = 49 + 93 which is... -> 71a = 142 which makes a = 142/71 = 2 so : a = 2 Hope that's what you were looking for! Your welcome if it was! :)

70a

12a

20

No, it is not.

That doesn't factor neatly. Applying the quadratic formula, we find two real solutions:24 plus or minus 6 times the square root of 14a = 46.44994432064365a = 1.5500556793563511

-7a-7b

It is:12a

12a

Add 8a to each side: -6a + 14 = 2 Subtract 14 from each side: -6a = -12 Divide each side by -6: a = 2. Job done.

a(-14-a) = 0 so a = 0 or a = -14

a=5 (14 x 5 = 70 ; 35 - 70 = -35)
