Question
Given the coupled systemx' + 6y = 3,
y' - x = 4,
a corresponding second order ODE in x alone would be Question 5 options: A) x'' + 6x = -24 B) x'' + 6x = -12 C) x'' + 6x = -8 D) x'' + 6x = -4 E) x'' + 6x = 4 F) x'' + 6x = 8 G) x'' + 6x = 12 H) x'' + 6x = 24 I) none of these Given the coupled system

Explanation / Answer
x' + 6y = 3,
differentiate
x'' + 6y' = 0
put y' - x = 4 => y' = 4 + x
x'' + 6*4 + 6x = 0
=>
x'' + 6x = -24
A) x'' + 6x = -24
