2x - 3x = -x
2x minus 3x is equal to -x.
x(3x - 2)
3x - x = (3 - 1)x = 2x
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.
2x+3y=13 3x-y=3 x=2
2x minus 3x is equal to -x.
2x minus 3x is equal to -x.
3x=2x-12x=-12
5x - 2x = 3x
6 - x + 7 - 3x - 5 = -2x - 10 ∴ x + 3x - 2x = 6 + 7 - 5 + 10 ∴ 2x = 18 ∴ x = 9
3x - 2x + 4 = 0 3x - 2x = -4 x = -4
x(3x - 2)
3x+7=2x-5 x=-12
3x - x = (3 - 1)x = 2x
3x^(2) +9x - 2x -6 Collect 'like terms'. Hence 3x^(2) + 7x - 6 Next write down all the factors of '3' and '6' Hence 3 ; 1' & 3' 6 ; 1,6 ; 2,3. From these pairs of number we select a pair from each coefficient, that add/multiply to '7' . Hence (3' x 3 ) & (1' x 2) ; NB 'dashes' (') to indicate source of numbers. Write up brackets (3x 2)(x 3) -2)(x + 3) Next we notice that the '6' is negative, so the two signs are different (+/-) The '7x' is positive , so the larger number takes the positive sign . Hence (3x - 2)(x + 3)
-2x -11y - 13
Let's dive into this problem: Given numbers/terms are: -2x and x.. We are asked to subtract both.. -2x-x = -(2+1)x = -3x.. Therefore, the answer is -3x..
