x = -14
x = -5
x+2(x+3) = 12 x+2x+6 = 12 x+2x = 12-6 3x = 6 x = 2 and y = 5
If I have this correct you are asking x^2 + 10^2 = 12^2 Then x=6.633249507108
If the equation is structured like this: (8/x)=(12/(x+2)) then x=4. If the equation is structured like this: (8/x)=(12/x)+2 then x=-2.
3x+12=x+48: 3x-x=-12+48 2x=36 x=18
so 3x + 2 = x + 12 ie 2x = 10 x =5
x = 12
2+x-4 = 12 x = 12+4-2 x = 14
x=12 because 12 over 6 is 2,and 2 plus 4 is 6.
-26
The value of x is 10
x = 4
X=1.42857142857143
4 x 2 + 4 = 12 x = 4
x = -5
x=2
X=2
