x in (-oo:+oo)
(-6/7)*(6*x+4) = (5/28)*x-15 // - (5/28)*x-15
(-6/7)*(6*x+4)-((5/28)*x)+15 = 0
(-6/7)*(6*x+4)+(-5/28)*x+15 = 0
(-5*x)/28-6/7*(6*x+4)+15 = 0
(-6/7*28*(6*x+4))/28+(-5*x)/28+(15*28)/28 = 0
15*28-6/7*28*(6*x+4)-5*x = 0
420-149*x-96 = 0
324-149*x = 0
(324-149*x)/28 = 0
(324-149*x)/28 = 0 // * 28
324-149*x = 0
324-149*x = 0 // - 324
-149*x = -324 // : -149
x = -324/(-149)
x = 324/149
x = 324/149
