6x + 9 + 2x = 8x + 9
7x + 7 + 6x - 9 = 13x - 2
-9
6x - 9 - x = 6Combine like terms on the left side:5x - 9 = 6Add 9 to each side:5x = 15Divide each side by 5:x = 3By the time you simplify it, you've solved it.
If that's 6x + 10, that factors to 2(3x + 5)
12x^2+10
6x^2
6x - 9 = 21 6x = 21 + 9 6x = 28 x = 28/6 Reduce to: x = 14/3
1+6x+6x+8 1+ 12x +8 12x + 9 = 21 + x
3xy^(3)2xy(6) = 6x^(2)y^(9).
-6x + y = 9 (+6x) -> y = 6x + 9
Following the correct order of operations, 8x + (1)(121) - (x/6x)(9)-x=8x+121-1.5-x=7x+119.5
