13x + 15 = 11x - 5 2x = -20 x = -10
it equals 13X.
13x
x + 13x + 10x = 50 - 6
-x2 - 11x + 26 = -(x2 + 11x - 26) = -(x2 - 2x + 13x - 26) = -[ x(x - 2) + 13(x - 2) ] = -(x + 13)(x - 2) = (x + 13)(2 - x)
13x + 15 = 11x - 5 2x = -20 x = -10
13x+9
Since 7x + 13x +2x + 8 is an expression (there is no equal sign), there is no answer as to what x equals. However, this expression can be simplified to 22x + 8.
13x
Y=13/11x + 12/11
it equals 13X.
13x
x + 13x + 10x = 50 - 6
2x - 13 x = 24 -11x = 24 -11x/-11 = 24/-11 x = -2 2/11
If you mean: 6x-4x-2+11x then it can be simplified to 13x-2
-x2 - 11x + 26= -x2 - 13x + 2x + 26= (2x - x2) + (26 - 13x)= x(2 - x) + 13(2 - x)= (2 - x)(x + 13)
2x - 13x + 42 = x +ax + b a + b = 2(x - 6.5x + 21) = 34 = a + b
