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
11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
11x(2x - 1) = 0 so either 11x = 0 or x = ½
X2+11x+11 = 7x+9 X2+11x-7x+11-9 = 0 x2+4x+2 = 0 Solve as a quadratic equation by using the quadratic equation formula or by completing the square: x = -2 + or - the square root of 2
-3x + 6 + 15x =11x + 8 ie -3x + 15x - 11x = 8 - 6 ie x = 2
If 6x + 10 = 11x , then x=2.
11x = 20x +1811x-20x=18x(11-20)=18-9x=18x=-2
2x - 13 x = 24 -11x = 24 -11x/-11 = 24/-11 x = -2 2/11
1st: Multiply each side by 11x. 2nd: the 11x under the 2 will be canceled out. 3rd: Now you are left with 2=14(11x) 4th: Multiply the 14 with the 11x, and your equation will look like: 2=154x 5th: Devide both sides by 154, and you are left with 2/154=x 6th: Simplify 2/154 to equal 1/77. The eauation will now be the answer! 1/77=x
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
-11x-27=-49 11x+27=49 11x=22 x=2
11x = 8x-6.............. 11x-8x = -6................... 3x= -6 x = -2
11x(2x - 1) = 0 so either 11x = 0 or x = ½

3x-7 = 14x-29 29-7 = 14x-3x 22 = 11x x = 2 Hope that helps!!;)
It is: -4x^2 +11x -6 equals (-4x+3)(x-2) when factored
11 x 2= 22 x+x=2 22 divided by 2= 11 22+11= 33 33-5=28
