1.Solve the following system by the substitution method. 3x+y=6 y=3x. Does it have solution set, many solutions or empty set.
(2). 4x+5y=48 x=y+3 ( 3). 9y-8x=-45 x-2y=3 (4) 4x+5y=19 x+y=5 (5)2x+y=8 (6) 2x+4y=4 x=9-2y (7) 15x-10y=1 15y=1+10x (8) 1/2X+2/3Y=-17/2 3x-y=9
(9) 1/5X+1/3Y=2/15 1/5X+4y=74/5 (10) 0.1x+0.9y= -5.8 0.3x-0.2y=2.9 (11) 0.07x-0.01y=0.1 0.27x+0.14y=11.1 (12) 3x+5y= -y 2x+y=0
(13) 5x+y=8 y=8-5x
