This is the second part of a three part problem. Consider the system of differential equations y1 7y1 + 2yz, -4y1 + y2- Verify that for any constants cj and c2, the functions y1 (t) cleft + Cze3t y2(t) -cleat - 2czest, satisfy the system of differential equations. Enter c, as c1 and c2 as c2. a. Find the value of each term in the equation y, = 7y1 + 2y2 in terms of the variable t. (Enter the terms in the order given.) b. Find the value of each term in the equation y, - -4y1 + y2 in terms of the variable t. (Enter the terms in the order given.)
