Answer:
Below
Step-by-step explanation:
(2x/x+3) + (x+3/x-5)
Transform: 2x(x-5) + (x+3)^2 / (x+3)(x-5)
Remove brackets and expand : 2x^2 - 10x + x^2 + 6x + 9 / x^2 - 5x + 3x - 15
Collect like terms : 3x^2 - 4x + 9 / x^2 - 2x - 15
Final answer: 3x^2 - 4x + 9 / x^2 - 2x - 15
The point that is 3/7 of the way between -4 and 17 is 5
(+3x+4y=2)
(+4x-4y=12)
-----------------
7x = 14
-----------------
7
X=2
3(2)+4y=2
6+4y=2
4y=-4
Y=-1.
Or you can plug x into the other equation.
4(2)-4y=12
8-4y=12
-4y=4
Y=-1.
7.4z-5(-1.6z+2.4)
7.4z+8z-12
15.4z-12
Hope this helps :)
