3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
3x + 2y = 7
(2, -1)
3x-2y-7=0
3x+2y = 1 2y = -3x+1 y = -1.5x+0.5
3x+2y=20 5x-2y=1 (3x+2y) + (5x-2y)= 20+1 3x+5x= 21....... 8x=21.........x=2 5/8 Subsitute x=3(2 5/8)+ 2y=20........... 7 7/8 +2y=20.........2y= 20- 7 7/8....... y=6 1/16
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
3x + 2y = 7
(2, -1)
3x-2y-7=0
3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0
3x+2y = 1 2y = -3x+1 y = -1.5x+0.5
3x+2y=6 2y=-3x+6 y=-1.5x+3
3x+2y=9 2y=9-3x y=-1.5x-4.5
y=16 x= -4
3x+2y-5=0 3x+2y=5 Im lost im only 12 work out the rest hope i helped
3x + 2y = 8 This is an equation. It could be the equation of a line.
