Answer:
x-2=x
-2=x
+
=x
x= -10
Step-by-step explanation:
x = 
± 
i
rearrange the equation and equate to zero
2x² - 6x = - 5 ⇒ 2x² - 6x + 5 = 0
this doesn't factor with integers, hence use the quadratic formula to solve
with a = 2, b = - 6 and c = 5
x = (6 ± √(36 - 40 ) )/4
= (6 ± √(-4) ) / 4
= (6 ± 2i ) / 4
x = ± i
To simplify, you just condense all of the values with the same variable, based on the signs of those values.
In this example,
6y + 5z + 8y - 3z
is the same as
6y + 8y + 5z - 3z
which can be simplified to
14y + 2z
which is the answer to your question.

13/15
Common denominator is 15, 1 3/15 minus 5/15 equals 13/15
Answer would be 180 cars.
Reason being if you take 24 and divide that by 2 you will get 12 and 12 times 15 is 180 or you could also do 24 times 7 then add 12 to get the 180 also
