Answer:
x - 5 = 3x + 1
-6 = 2x

Step-by-step explanation:
Answer:
15 (I think)
Step-by-step explanation
6 x 25 = 150
20% of 150 = 30
10% of 150 = 15
30 - 15 = 15

Simplifying the above expression we shall proceed as follows:
<span>x-2/(x^2+4x-12)
factoring out the denominator we get:
</span>x^2+4x-12
=x^2-2x+6x-12
=x(x-2)+6(x-2)
=(x+6)(x-2)
thus our expression will be:
(x-2)/[(x+6)(x-2)]
simplifying the above we get:
1/(x+6)
Answer: 1/(x+6)
