1-(3*x) = ((21*x+37)^1)/2 // - ((21*x+37)^1)/2
1-(((21*x+37)^1)/2)-(3*x) = 0
1-((21*x+37)/2)-3*x = 0
(-1*(21*x+37))/2-3*x+1 = 0
(-1*(21*x+37))/2+(-3*2*x)/2+(1*2)/2 = 0
1*2-1*(21*x+37)-3*2*x = 0
2-27*x-37 = 0
-27*x-35 = 0
(-27*x-35)/2 = 0
(-27*x-35)/2 = 0 // * 2
-27*x-35 = 0
-27*x-35 = 0 // + 35
-27*x = 35 // : -27
x = 35/(-27)
x = -35/27
x = -35/27
