If you mean 8x+5y = 100 then it is a straight line equation
- 8x + 8x = 0 so question is meaningless.
Y-8x plus 9y equals 10y-8x.
16x + 3
8x + x = 9x
X2 + 8x + 16 = 10x +16x2 + 8x + 16=2x + 8x + 16=10x + 16
When simplified it is: 1-8x
(8x + 3)2 ie (8x + 3)(8x + 3)
3x-3x+4x^2+8x=4x^2+8x
8x plus 4y equals 5 is 8x + 4y = 5.
4x+8x+3 = 12x+3
It is 7+8x simplified
7y+ 8x + 4= 20 + 8x- 8x - 8x7y + 4 = 20- 4 - 47y=16/7 /7y= 2.28the /7 means divide by 7 :)
