Solve the system using substitution: y = 3x+8; 5x+2y = 5

(-1, 5)

Solve the system using substitution: 2y = x+7; x = y - 4

(-1, 3)

Solve the system using substitution: -3x -4y = -2; y = 2x - 5

(2, -1)

Solve the system using elimination: 2x+3y = 20; -2x+y = 4

(1, 6)

Solve the system using elimination: 5x - 3y = -1; 3x+2y = 7

(1, 2)

Solve the system using elimination: x+y = 2; x-y = 14

(8, -6)

Solve the system using graphing: y = 2x+4; y = -3x+4

(0, 4)

Solve the system using graphing: x-y = 5; x + 2y = - 4

(2, -3)

Solve the system using graphing: y = 1/4x ; y = 1/4x - 3

No solution!!
