Solve the following equations by determinants:
4x - 3y = 10; 3x - 3y = 7 a. 21 21 x = ÄÄ y = ÄÄ 51 2 b. 2 x = 5 y = ÄÄ 21 c. 31 2 x = ÄÄ y = - ÄÄ 21 21 d. 2 x = 3 y = Ä 3 e. 51 2 x = - ÄÄ y = ÄÄ 21 21
Solve using any appropriate method. If the system has an infinite number of solutions, use set-builder notation to write the solution set. If the system has no solution, state this.5x + 5y = 69x + 9y = 18
A. (18, 9) B. {(x, y)|5x + 5y = 6} C. (1, 1) D. No solution
