2y=4x+1 sp y=2x+1/2 so the slope or gradient is 2

{-1,-2}
4x + 10 + 3x = 40 - 3x 4x + 10 + 3x + 3x = 40 20x = 40 x = 2
x - 2
6x - 4y
It is possible.
2y=4x+1 sp y=2x+1/2 so the slope or gradient is 2
3x - 12 = 10x - 15 - 6x -10 3x - 12 = 4x -25 3x + 13 = 4x 13 = 4x - 3x 13 = x None?
x= -11
4x - 7 = 5 + 7x x = -4
minus 4 plus 9 = 5, so 5x
It is: minus 1.25

x= Negative 4
6x plus 3y minus 2x plus 5y equals 4x plus 8y.
The equation 4x + 5 = 2 has the solution 4x = -3 and x = - 3/4 (minus 3/4).
