Question 763092
Solve for x
 
(1)  x-1/4-2x-3/3=-1/12
x - 1/4 - 2x - 1 = -1/12\
-x - 5/4 = -1/12
-x = -1/12 + 5/4 = -1/12 + 15/12
-x = 14/12
x = -7/6
======================
(2)  2/6x-19=3/2x-11
------
Multiply thru by 6x
2 - 19*6x = 9 - 11*6x
2 - 114x = 9 - 66x
2 = 9 + 48x
48x = -7
x = -7/48
=============================
(3)  2x+3/3x+4=7/10
2x + 1/x + 4 = 7/10
2x + 1/x = -33/10
{{{2x^2 + + 33x/10 - 1 = 0}}}
