Question

5/8x+1/16x=5/16+x
the solution is x=?
help please??

Answer 1

is the x in the denominator?

Answer 2

5/8x+1/16x=5/16+x
(10+1)/16x=5/(16+x)
11(16+x)=5*16x
176+11x=80x
176=69x
x=176/69

Answer 3

5 1 5
--- + ----- = ----- + x
8x 16x 16

Multiply all terms by 16x, we get

10 + 1 = 5x + 16x^2
11 = 5x + 16x^2

16x^2 + 5x - 11 = 0
16x^2 + 16x - 11x -11 = 0
16x(x + 1) -11(x + 1) = 0
(16x - 11)(x + 1) = 0

This is possible if either (16x - 11) or (x + 1) is zero

If 16x - 11 = 0 ==> 16x = 11 ==> x = 11/16
If x + 1 = 0 ==> x = -1

Therefore x = 11/16, -1

Answer 4

harikat so 176/69 is wrong

Answer 5

is x in the denom or not?
(I've solved as it is)
