Yes. 6 - y = 2x -y = 2x -6 y= -2x +6 If plotted on a graph, the line will have a gradient -2, and will intercept the axes at (0,6) and (3,0).

2x to the fourth power minus 162 equals -146

-2x=2y-4 2x-y=-5 Answer=(-1,3)

2x to the fourth power minus 162 equals -146
-2x plus 3y equals 1
3x=2x-12x=-12
y=2x means that the line on the graph will travel through the coordinates (0,0) (2,1) (4,2) (6,3) etc. Basically it will go up 2x's for every 1y.y=2x is a linear function.
y = 2x + 5x - 12 = 7x - 12 So the zero is 12/7 = 1.7143 (approx)
x = 4 and y = 7
