3y - 3 = 2y + 5 3y - 2y = 5 + 3 y = 8

Multiply first equation by 2: 4x - 2y = 20 Subtract second equation: x = 12, so y = 14.

If: x-2y = 1 then x = 2y+1 If: 3xy -y^2 = 8 then 3*(2y+1)*y -y^2 = 8 So: 6y^2 +3y -y^2 = 8 or 5y^2 +3y -8 = 0 Factorizing the above: (y-1)(5y+8) = 0 meaning y = 1 or y = -8/5 Solutions by substitution are: (3, 1) and (-11/5, -8/5)

Yes.

4x-2y=16 has the solution points (0,-8) and (4, 0) at the coordinate axes, and wherever y= 4(x-4).

-2y=x+8 is the answer

2y=8..... y=4

Solve for y: 2x+2y=8 2y=-2x+8 y=-x+4 f(x)=-x+4 I think that's what you mean.

If 3y = 12, 2y = 8

-4x=2y-16 +16 +16 (-4x+16)=(2y) /2 /2 y=-2x+8

It's a simple linear equation in 'y'.To find the solution:7y - 8 = 2y + 37Subtract 2y from each side of the equation:5y - 8 = 37Add 8 to each side:5y = 45Divide each side by 5:y = 9

If: 2y-10 = 8 Then: y = 9

y=4

When graphed, or written in the form [ y = f(x) ], the slope is -3 .

since Y=8 and your equation is 2Y then it would be 2X8=16.

3x + 2y = 8 This is an equation. It could be the equation of a line.
