(-X+2/3)-(2X+5/4)=5
-X+2/3-2X-5/4=5
-3X=5-2/3+5/4 FIND A COMMON DENOMINATOR FOR ALL 3 VALUES OTHER THAN THE X VALUE
-3X=60/12-8/12+15/12 NOW COMBINE ALL THE FRACTIONS
-3X=(60-8+15)/12
-3X=67/12 NOW MULTIPLY BOTH SIDES BY -1/3
-3*X(-1/3)=67/12*(-1/3)
X=67/-36
X=-67/36
PROOF
(-[-67/36]+2/3)-(2*-67/36+5/4)=5
67/36+2/3+134/36-5/4=5
(67+134)/36+2/3-5/4=5
201/36+2/3-5/4=5
201/36+24/36-45/36=5
(201+24-45)/36=5
180/36=5
5=5
