you just supplement the 1.8 for the v so you get the problem 1.8 - 0.6

If you mean: 18*27 = 18m+18*7 then the value of m works out as 20
As an algebraic expression it is simply: 18-x
That's going to depend completely on the value of 'x', and every time 'x' changes, the value of that expression also changes. Whatever 'x' happens to be at the moment, your expression is [ - 2 / (18+x) ].
72/c where c= 4 is the same as 72/4 (which =18)
18² is the same as 18 x 18, which equals 324.
-6
a=8 if you mean 144/a=18
20
-18 / 6 = -3
x=18
18
It is a false statement and therefore has the value 0.
