Given : 5-3x : 5x+7 = 1 : 125
To Find : Solve for x
Solution:
5-3x : 5x+7 = 1 : 125
=> ( 5 - 3x)/(5x + 7) = 1/125
Cross multiply
=> 125 (5 - 3x) = 1(5x + 7)
=> 625 - 375x = 5x + 7
=> 625 - 7 = 5x + 375x
=> 618 = 380x
=> x = 618/380
=> x = 309/190
if Question is :
5⁻³ˣ : 5ˣ⁺⁷ = 1: 125
=> 5⁻³ˣ / 5ˣ⁺⁷ = 1/125
=> 1/5ˣ⁺⁷⁻⁽⁻³ˣ⁾ = 1/5³
=> 1/5⁴ˣ⁺⁷ = 1/5³
=> 4x + 7 = 3
=> 4x = - 4
=> x = - 1
