c = 18u + 85
c - 85 = 18u
(c - 85)/18 = u
this can not be solved un less with another equation
A single linear equation in two variables cannot be solved.
Since the second equation is already solved for "y", you can replace "y" by "9" in the other equation. Then solve the new equation for "x".
One linear equation in two variables (x and y) cannot be solved.
It can be solved by using the quadratic equation formula.

There is no equation (nor inequality) to be solved!
It cannot be solved because the discriminant of the quadratic equation is less than zero
There is no equation nor inequality in the question and so there is nothing that can be solved. Please resubmit your question spelling out the symbols as "plus", "minus", "equals".
A single linear equation in two variables cannot be solved: you need two independent equations.
There is no equation or inequality in the question that can be solved! There is an expression but expressions cannot be solved.
x plus 0.068 is not an equation -- it has no equal sign -- so it can't be solved.
k equals 5.6
