Answer:this i going to took long time
Step-by-step explanation:Simplifying
3x + -2y = -16
Solving
3x + -2y = -16
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '2y' to each side of the equation.
3x + -2y + 2y = -16 + 2y
Combine like terms: -2y + 2y = 0
3x + 0 = -16 + 2y
3x = -16 + 2y
Divide each side by '3'.
x = -5.333333333 + 0.6666666667y
Simplifying
x = -5.333333333 + 0.6666666667y
Answer:
Factorise and split the denominator:
1/(x^3 + 8x) = 1/(x(x^2+8)) = (1/x) * (1/(x^2+8))
now say
(a/x) + ((bx+c)/(x^2+8)) = (x+16)/(x^3+8x)
so
(x^2+8)a + (bx+c)x = x + 16
a must be 2 to get the + 16
2x^2 + 16 + bx^2 + cx = x + 16
b must be -2 to get rid of the 2x^2
c must be 1 to get the x
