I assume you wish to simplify the expression (x - 2)/(3x + 9) . (2x + 6)/(2x - 4) = (x - 2)(2x + 6) / [(3x + 9)(2x - 4)] = 2(x - 2)(x + 3) / [6(x + 3)(x - 2)] = 1/3.
6x^2
2x3x-4= -24
This will simplify to 27 - 12x, assuming the original equation was 7-34-2x-10x.* * * * *No, it will not! If the assumption is correct, it will simplify to -27-12x.

X = 0.8
You can divide the integers in this case - 4 divided by 2 and 9 divided by 3. You would get 2 over x plus 3 over x. 4/2x + 9/3x = 2/x + 3/x = 5/x
OK, SO 15x-3 = 2x+1 15x - 3 + 3 = 2x + 1 + 3 (add three to each side) 15x=2x+4 (simplIfy) 15x-2x=2x-2x+4 (subtract 2x from each side) 13x=4 (simplify) (13x/13)=(4/13) (divide each side by 13) x≈0.30769231
By collecting like terms: 8z+4-2x

To simplify an equation is to combine like terms, but you do not solve it for example: simplify 3X+4-X-6 2X-2
