13x + 15 = 11x - 5 2x = -20 x = -10
2x2 + 11x + 15 = (x + 3)(2x + 5).
If you mean -11x-5(x-12) = 252 then the value of x works out as -12
4x-5.
20X - 3 + 3X = 11X + 5 - 8 put those like terms together on the left 23X - 3 = 11X + 5 - 8 like terms together on the right 23X - 3 = 11X - 3 this equation admits of no solution, so is not true X would = 0
2x2 + 15 = 11x ? Can be only for some values of x.2x2 + 15 = 11x subtract 11x to both sides2x2 - 11x + 15 = 0(2x - 5)(x - 3) = 02x - 5 = 0 or x - 3 = 0x = 5/2 or x = 3
If you mean: 2x2+11x+15 then it is (2x+5)(x+3) when factored
13x + 15 = 11x - 5 2x = -20 x = -10
2x2 + 11x + 15 = (x + 3)(2x + 5).
You have to experiment with different factors of 2, and different factors of 15. In this case, 2x2 - 11x + 15 = (2x - 5) (x - 3)
12x - 5 = 11x + 5(1) add 5 to both sides:12x - 5 + 5 = 11x + 5 + 512x = 11x + 10(2) next subtract 11x from both sides:12x - 11x = 11x - 11x + 10x = 10
12x = 11x - 5, subtract both sides by 11x x = -5
Write as an equation with division before subtraction. 5/11x-7=2 5/11x=9 mult both sides by 11x 5=99x 99x=5 x=5/99
If that's - 11x - 20, the answer is (4x + 5)(x - 4). If that's + 11x + 20, it gets ugly in a hurry.
2x2 = 11x - 5 2x2 - 11x + 5 = 0 (x - 5)(2x - 1) = 0 x = 5 or 0.5 Check: 2 x 25 = 55 - 5 ok 2 x 0.25 = 5.5 - 5 ok The integer is 5.
If you mean -11x-5(x-12) = 252 then the value of x works out as -12
4x-5.
