Looks to me like you want to solve for y.[(.44 - y) / 23.95] + (y / 56.11) = .44rewrite(.44/ 23.95) - (y / 23.95) + (y / 56.11) = .44subtract the first term on the left from both sides and combine the remaining like terms on the left.-0.02393...y = 0.421628...divide both sides by the coefficient of y.y = -14.61812...I think that should do it.
