Such an equation would represent an ill-posed problem for all positive time (i.e. the solution is not defined). The irreversibility of diffusive processes is closely related to the second law of thermodynamics.

y = 2 (Divide each side of the equation by -45)
If you solve for y with no coefficient, you should have an equation in the form of y = mx + b, where m is the slope and b is the y intercept.
Set up the equation and solve: x + 5 = -13 (next subtract 5 from each side of the equation to solve for x) x = -18
b = 14
For example ?x+20=50x then solve: 50x-20=30x 30x/x=30 then the answer is 30 you just have to dived the answer by x
