Systems of Equations: Problems 3

Problem : Solve the following system of equations:

4x - 4y	=	-4
3x + 2y	=	12

(x, y) = (2, 3)

Problem : Solve the following system of equations:

2y	=	16 + 4x
3x + 5y	=	27

(x, y) = (- 1, 6)

Problem : Solve the following system of equations:

3x + 4y	=	12
18 - 2x	=	6y

(x, y) = (0, 3)

Problem : Solve the following system of equations:

4y - 6x	=	10
6y	=	15 + 9x

The system is dependent. Any ordered pair (x, y) satisfying 2y = 3x + 5 is a solution.
