Me plese if a system has exactly one solution it is called consistent inconsistent independent dependent what is the approximate solution of the following system of equations? graph of lines y equals negative x plus 3 and y equals negative one-half x plus 1 (4, -1) (4, 1) (-1, 4) (1, -4) solve the following system of equations by using the substitution method. 2x – 3y = -1 y = x – 1 (3, 4) (2, 3) (4, 3) inconsistent solve the following system of equations by using the substitution method. 3y – 2x = 11 y + 2x = 9 (2, 5) (-2, -5) (4, 5) inconsistent solve the following system of equations by using the elimination method. -2x + 9y = -13 6x – 3y = 15 (1, 3) (4, 5) (2, -1) (-2, -1) solve the following system of equations by using the elimination method. x – y = 11 2x + y = 19 (1, 10) (-1, -1) (12, 2) (10, -1) solve the following system of equations using matrices. 4x + 5y = -7 3x – 6y = 24 (1, 4) (2, -3) (5, 6) (3, 4) solve the following system of equations using matrices. x + y = 1 2x + 5y = 4 (1/3, -2/3) (1/3, 2/3) (2, 1) (-3, 0) the sum of two numbers is 7. four times the first number is one more than 5 times the second. find the two numbers. 2 and 1 4 and 3 5 and 7 2 and 3
