For x-2x= 3x-43x+1 x-2x= -x and 3x-43x+1 = -40x+1 so -x= -40x+1 subtract -x from both sides 0= -39x +1 -1 = -39x so 1=39x so x=1/39
14x2 - 39x - 35 = (7x + 5)(2x - 7)
(7x + 5)(2x - 7)(2x-7)(7x+5)
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
Solve for y: f(-5)=13+2x

14x2 - 39x - 35 = (7x + 5)(2x - 7)
(2x - 7)(7x + 5)
It is a quadratic expression and when factored it is: (7x+5)(2x-7)
It is (7x+5)(2x-7) when factored
(7x + 5)(2x - 7)(2x-7)(7x+5)
2x + 5 - 5 = 2x. You can not solve for x because this is not an equation.
Solve for y: f(-5)=13+2x
2x+a=p 2x=p-a x=.5p-.5a
2x + 3 is an expression that is already in simplest form; you cannot "solve" it.
If 2X - 87 = 0 Then: 2X = 87 X = 43.5
