8x + 2y = -10
As all terms have a factor of 2 then the values can be reduced accordingly.
4x + y = -5
If required, the equation can be re-written to show x or y as the subject.
4x + y = -5 : 4x = -y - 5 : x = (-y -5)/4........this can also be written as x = (y + 5)/-4
4x + y = -5 : y = -4x - 5

Solve 4x plus 3y equals 8x plus y for y?
4x + 3y = 8x + y so 3y - y = 8x - 4x ie 2y = 4x so y = 2x
8x plus 2 equals 6x plus 10?
8x+2=6x+10 8x-6x=10-2 2x=8 x=4 Therefore, x=4.
10x-5y plus 2x-3y?
10x - 5y + 2x - 3y = 12x - 8y
What is the Y intercept of 8x-2y-20?
If you mean: 8x-2y = -20 then y = 4x+10 whereas 4 is the slope and 10 is the y intercept
What is the slope intercept form of the equation -8x-2y equals 16?
-8x -2y = 16 Algebraically rearrange into the form ' y = mx + c'. Hence 2y = -8x - 16 Divide both sides by '2' y = -4x - 8 Hence 'm' the slope is '-4' 'c' the y-intersect is '-8'. NB The equation can be in numerous forms : - -8x - 2y - 16 = 0 8x + 2y + 16 = 0 -8x = 2x + 16
