Perpendiculat straight lines.

-3x + 2y = 12-3x + 3x + 2y = 3x + 122y = 3x + 122y/2 = 3x/2 + 12/2y = (3/2)x + 6

For 4x + 2y = 6The X intercept is 1.5The Y intercept is 3

The solution is (x, y, z) = (2.5, 1, 2.5).

x = -4 and y = 4

2y(x+2)=

-2y=x+8 is the answer

x + 2y = x + 2y Y and X aren't compatibles.

This means that 2y - 3 = 2y + 4 which is not possible.

(12, 1)

Both of them are equations!The solution is (x, y) = (2, 1).

x = 11/7 and y = 12/7

x=2y-1

x = -8, y = 10

They are straight lines.

If the two equations are (i) 4x + 2y = 12 and (ii) x + 2y = 6, proceed as follows: Rewrite (ii) as x = 6 - 2y; substitute this expression for x into (i) to result in 4(6 - 2y) + 2y = 12, or 24 - 8 y + 2y = 12, or - 6 y = 12 -24 = -12, or y = -12/-6 = 2. Then, back to (ii) again, x = 6 - 2(2) = 2.
