It is a straight line equation that needs to be rearranged into slope-intercept form as follows:- 8x+20y = -80 20y = -8x-80 y = -0.4x-4
It has no solution!!!The two equations contradict.If you recast the first in terms of x2x-5y=92x=5y+9x=2.5y+4.5Then substitute for x in the second equation8x-20y=58(2.5y+4.5)-20y=520y+36-20y=536=5 (False)which is not true - so the equations have differing values for x and/or y and so are not solveable.
12y - 4 = 7y + 165y = 20y = 4
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
x2 + 10x + y2 + 20y - 19 = 0 x2 + 10x + y2 + 20y = 19 Complete the squares on the LHS: x2 + 10x + 25 + y2 + 20y + 100 = 19 + 25 + 100 = 144 Simplify LHS: (x + 5)2 + (y + 10)2 = 122 This is the equation of all points whose distance form the point (-5, -10) is 12 units. That is, the circle with centre (-5, -10) and radius = 12 units.

x isn't in the calculation so it cant be solved.
4x + 20y
12y - 4 = 7y + 165y = 20y = 4
5x + 4y = 204y = -5x + 20y = (-5/4)x + 5
If: 9y-20y = 25 Then: y = -25/11
12x - 9y = 6, 12x + 20y = 64 29y = 58 y = 2 x = 2
LCM(20y, 14y^2) = 140y^2
x2 + 10x + y2 + 20y - 19 = 0 x2 + 10x + y2 + 20y = 19 Complete the squares on the LHS: x2 + 10x + 25 + y2 + 20y + 100 = 19 + 25 + 100 = 144 Simplify LHS: (x + 5)2 + (y + 10)2 = 122 This is the equation of all points whose distance form the point (-5, -10) is 12 units.

sqrt(8xy2) * sqrt(20y) = 2y*sqrt(2x)*sqrt(20y) = 4y*sqrt(x)*sqrt(10y) = 4y*sqrt(10xy)
140y
