Answer to Question #55750 in Linear Algebra for MUSTY FRESH

Question

1 Solve the equations 5x + 2y = 14, 3x - 4y - 24.
x = 4, y = -4
x = 4, y = -2
x = 4, y = -3
x = 4, y = 3
2 Solve the linear equation 2x+3y=1, 5x+7y=3.
x=2, y=-1
x=4, y=-2
x=2, y=-2
x=5, y=-3
3 Solve the linear equations 2x+4y=10 and 3x+6y=15.
x=5-2a,y=a
x=5-2a,y=4
x=5,y=a
x=-2a,y=a
4 Solve the set of linear equations by the matrix method : a+3b+2c=3 , 2a-b-3c= -8, 5a+2b+c=9. Sove for c
