Yes it can be solved and X=0.
Because it is "solved for x", x will be by itself on one side of the equation. On the other side will be what x equals.
It can't be solved without an equals sign somewhere.
If x equals the square root of ...., then you already have solved for x
x = 9
When solved: x = 6 and y = 3
Solved for y: y=(3x-13)/5 Solved for x: x=(5y+13)/3
x isn't in the calculation so it cant be solved.

x = 9/2 or x = -2 Solved by using the quadratic equation formula.
X = 135 and y = 15 Solved by addition and substitution
