Respuesta :
2nd Order because it contains a 2nd derivative ,y''
Linear because the y term is linear, in other words the y has no exponent, nor is it inside of a log or trig function.
ex:
ln(y) or sin(y) or e^y

The order of the given ordinary differential equation.
(1 − x)y'' − 7xy' + 5y = cos x is 2nd Order.
2nd Order because it is 2nd derivative function.
What is differential equation ?
Differential equations refers to the study of their solutions means the set of functions that satisfy each equation and the properties of their solutions.
Given : (1 − x)y'' − 7xy' + 5y = cos x
Here, according to the given differential equation is Linear In other words the y has neither Exponent nor is inside of a logarithmic or Trigonometric function.
For example:- [tex]\rm log(y) or\; sin(y) \;or\; e^y[/tex]
