If you mean: 16x-4y-8x+6y then it is 8x+2y in like terms
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1

Centre of circle: (2, 1.25) Slope of line: 9/4 Equation of line: y-1.25 = 9/4(x-2) => 4y-5 = 9x-18 => 4y = 9x-13
3x + 6y + 6x = 9x + 6y which can be factorised as 3(3x +2y)
If you mean: 16x-4y-8x+6y then it is 8x+2y in like terms
Put in this form to see. Y = mX + c 3X - 4Y = - 3 - 4Y = - 3X - 3 Y = (3/4)X + 3/4 --------------------- 8X + 6Y = 14 6Y = - 8X + 14 Y = (- 4/3)X + 7/3 ----------------------- Closer to perpendicular than anywhere near parallel!
-9x+6y = 54 6y = 9x+54 y = 1.5x+9 slope = 1.5
8x plus 4y equals 5 is 8x + 4y = 5.
9x-6y-(12*2y)=0 9x-6y-24y=0 9x-30y=o 9x=30y 3x=10y y=0.3x x=10/3y
9x + 3x - 9x = 6 + 8x - 113x = 8x - 11-5x = -11x = 2.2 or 11/5
8x - 6y = 184x - 6y = 6from the first equation:6y = 8x - 18substitute this value in the second equation:4x - (8x - 18) = 64x - 8x + 18 = 6-4x = 6 - 18-4x = -12x = 3Solve for y :8 x 3 - 6y = 1824 - 6y = 186y = 6y = 1
8x+9=9x-18+9 = 8x+9=9x-9 = 1x=0 (:
8x - 9 = 9x - 5 8x - 8x - 9 = 9x - 8x - 5 -9 = x - 5 -9 + 5 = x - 5 + 5 -4 = x
-8x + 4y = 28 Add 8x to each side: 4y = 8x + 28 Divide both sides by 4: y = 2x + 7
8x + 9x = x(8 + 9) = x(17) = 17x
6y 10+4y subtract 4y from each side 2y 10 divide both sides by 2 y = 5
