Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2

If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
5x-1+2= 5x+1
Here is the work for that problem: 5x+ 2=12 5x= 12-2 5x=10 x= 2
5x + 2 = 22 5x = 22 - 2 5x = 20 5x/5 = 20/5 x=4
5x-2 = 3x-6 5x = 3x - 6 +2 5x = 3x - 4 5x - 3x = -4 2x = -4 x = -2

If your equation is 5x-2=4x+4 Then this is how you solve it... 5x-2=4x+4 5x-2+2=4x+4+2 5x=4x+6 5x-4x=4x-4x+6 x=6 Your x=6
If you mean 5x+2 = 12 then 5x = 10 and the value of x is 2
5x-5 = -3 5x = -3+5 5x = 2 x = 2/5
If you mean: 5x(3x+2)-8x-7x then the expression can be simplified to 15x^2 -5x
Derivative with respect to 'x' of (5x)1/2 = (1/2) (5x)-1/2 (5) = 2.5/sqrt(5x)
