Question

Rewrite the system of differential equations given below as an equivalent system of first-order differential equations. Use the variables x1=x x2=x' x3=y etc. (so that your equations will have the form x2'=x3, etc.: denote subscripts by appending the subscript: x1= x1). System to rewrite: 0=x''−30x+15y 0=y''+5x−24y (Note that primes denote differentiation with respect to t.)
x1' =
x2' =
x3' =
x4' =
