(2/3)*((4/3)*x+1/2) = (-1/3)*((5/2)*x+7/2) // - (-1/3)*((5/2)*x+7/2)
(2/3)*((4/3)*x+1/2)-((-1/3)*((5/2)*x+7/2)) = 0
(2/3)*((4/3)*x+1/2)+(1/3)*((5/2)*x+7/2) = 0
2/3*(4/3*x+1/2)+1/3*(5/2*x+7/2) = 0
2/3*(4/3*x+1/2)+1/3*(5/2*x+7/2) = 0
31/18*x+3/2 = 0
31/18*x+3/2 = 0
31/18*x+3/2 = 0 // - 3/2
31/18*x = -3/2 // : 31/18
x = -3/2/31/18
x = -27/31
x = -27/31
