solve system of equations

Solve system of equations. Determine whether the system is consistent and independent, consistent and dependent, or inconsistent by using augmented matrices. 2 x + 5 y = 11 4 x - 3 y = 9 => (1, 3) or (3, 1) or (- 1, 4) or ( 1 2 , 2)..

Jason's allowance lets him save $6 per week. He wants to buy a music system with his savings. His parents agree to contribute $86 upfront. The music system costs $158. Solve the equation 6 w + 86 = 158 and find the number of weeks he has to save money to buy ..

Solve the system of equations. 3 x + 4 y = 8 x - 6 y = 10 Determine whether the system is consistent and independent, consistent and dependent, or inconsistent by using augmented matrices. => (4, - 1); consistent and independent or (0, 0); inconsistent or (4,..

Use Cramer's rule to solve the system of equations. 7.5 x - 3.4 y = 38.2 - 0.2 x + 2.2 y = 3.2 => (- 6, 2) or (6, - 2) or (6, 2) or (- 6, - 2)..

Solve the system of equations by using an inverse matrix. 125 x - 24 y = - 625 26 x - 5 y = - 130 => (- 5, 1) or (5, 0) or (0, - 5) or (- 5, 0)..

Solve the system of equations by using an inverse matrix. 5 x + 9 y = 2 x + 2 y = 1 => (9, 10) or (-5, 3) or (3, 9) or (3, -5)..

Solve the system of equations by using an inverse matrix. 50 x - 9 y = - 100 11 x - 2 y = - 22 => (- 2, 1) or (- 2, 0) or (0, - 2) or (2, 0)..

Solve the system of equations using Cramer's rule. 13 x + y + 156 = 0 x + 12 y + 12 = 0 => (12, 0) or (0, 12) or (0, - 12) or (- 12, 0)..

Solve the system of equations by using the multiplicative inverse of a matrix. x + y = 11 x - y = 1 => (5, 6) or (11, 5) or (6, 5) or (- 5, - 6)..

Solve the system of equations by using the multiplicative inverse of a matrix. 2 x + y - z = - 1 x - y - 2 z = - 2 2 y - z = 2 => (0, 2, 0) or (1, 0, 2) or (2, - 1, 2) or (- 1, 1, 0)..
