THe LCD is x(x^2 - 4)
so multiplying through by this we get:-
2x(x + 2) + 7x = 5(x^2 - 4)
2x^2 + 4x + 7x = 5x^2 - 20
3x^2 - 11x - 20 = 0
(3x + 4)(x - 5 ) = 0
so x = 5 , -4/3
Its the second choice
Answer:
1. (2, -9) 2. (10, 10)
Step-by-step explanation:
We basically have to cancel values on both sides until they are both on common ground.
7 + 3x = 5x + 13
-7 from both sides...
3x = 5x + 6
-5x from both sides...
-2x = 6
/-2 from both sides...
x = -3
Hope this helps!
Answer:
c= -2/3
Step-by-step explanation:
c+8 = -11c
C = -11c -8
c+11c = -8
12c = -8
divide both sides by 12
c= -2/3
