x in (-oo:+oo)
(1/4)*(x+2) = 4*x-(6*(2-x))-7 // - 4*x-(6*(2-x))-7
(1/4)*(x+2)+6*(2-x)-(4*x)+7 = 0
(1/4)*(x+2)+6*(2-x)-4*x+7 = 0
1/4*(x+2)+6*(2-x)-4*x+7 = 0
1/4*(x+2)+6*(2-x)-4*x+7 = 0
7-23/4*x-4*x+25/2 = 0
7-39/4*x+25/2 = 0
39/2-39/4*x = 0
39/2-39/4*x = 0
39/2-39/4*x = 0 // - 39/2
-39/4*x = -39/2 // : -39/4
x = -39/2/(-39/4)
x = 2
x = 2
