10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....
You can only simplify, and by the way you wrote it, it is a bit confusing. I'll assume you mean: 8y + 2 - 18y -5. In order to do this you must combine like terms, or the same things. We can combine 8y and -18y, as they are both y. 8y - 18y = -10y. Now we can combine 2 and -5, as they both are plain. 2 - 5 = -3. Your final answer would be: -10y - 3.
6x+14y+8x-18y = 14x-4y
18x + 18y - 4
18y+48+5y+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
10y + 8y = 18y = 15 y = 15/18 y = 5/6 = 0.833333.....

6x+14y+8x-18y = 14x-4y
18x + 18y - 4
18y+48+5y+15 = 270 18y+5y = 270-48-15 23y = 207 y = 9
The expression is equivalent to 23y - 3.
9x+18y = 36 18y = -9x+36 y = -1/2x+2 which is now in slope intercept form the slope being -1/2
3(y + 4)(y + 2)
6y3 + 48y2 + 90y
6x +108=18y y=6x/18+108/18 y=x/3+6
18y-8 = 10
(x - 2)(9y - 2)
