2 Points ZA 2 Which system of equations is represented by the matrix below? 5 -7115 L- 307 O A. 5x + 7y = 15 -3x = 7 O B. 5x-7y = 15 3x= 7 O C. 5x-7y= 15 -3x = 7 SUENT PREVIOUS re to search O
because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
Which of these equations, when solved, gives a different value of x than the other three? a9.1 = -0.2x + 10 b10 = 9.1 + 0.2x c10 – 0.2x = 9.1 d9.1 – 10 = 0.2x
