3x+2y-5=0
3x+2y=5
Im lost im only 12 work out the rest hope i helped
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
3x + 2y = 8 This is an equation. It could be the equation of a line.
4x-2y+3x+2y When simplified: 7x
x+2y-6=z -z -z x+2y-z-6=0 +6 +6 ---------> x+2y-z=6 3y-2z=7 ---------> 0x+3y-2z=7 4+3x=2y-5z -3x -3x ---------> -3x+2y-5z=4 Put them into a matrix, for x,y,z and their answers. Solve for [A]-1[B], and the answer comes to: x= 1.75, y= 1.5, and z= -1.25
The ordered pair is (5, 4).
(2, -1)
(4, -1)
-3x + 2y = 9 2y = 3x + 9y = 1,5x + 4,5
3x + 2y = 7
3x-2y-7=0
3x+2y=9 2y=9-3x y=-1.5x-4.5
3x+2y = 1 2y = -3x+1 y = -1.5x+0.5
3x+2y=6 2y=-3x+6 y=-1.5x+3
3x = 2y + 7 The standard form is: 3x - 2y - 7 = 0
Multiply the first equation by -3
3x + 2y = 8 This is an equation. It could be the equation of a line.
3x + 2y = 12 ie 2y = 12 - 3x so y = 6 - 3x/2
