Question

Solve for x in the proportion 9 over 27 times x equals x over the quantity x plus 3.

x = 2 and x = 0

x ≈ −2.48 and x ≈ 2.48

x ≈ −0.85 and x ≈ 1.18

x ≈ −6 and x ≈ 6.16

Answer 1

If it means 9/27x = x/x+3
solving the quadratic 3x^2-x-3,
c is the answer

Answer 2

Solve for x in the proportion 9 over 16 equals x over 192.

x = 21

x = 12

x = 108

x = 1728
