That's correct. Now solve for x by setting 9x2 equal to each solution of y.

# Can long strings always snap?
In quantum chromodynamics, long flux tubes will always snap because a quark-antiquark pair gets created from the vacuum, and hadronization results with a quark attached to each new end.
In string theory, if we try to stretch a single string out a long distance, will it also snap? If op... | {} |

Since Neon exists as a monoatomic gas, the intermolecular Van der Waal's forces are very weak indeed.
However, when it is cooled to a sufficiently low temperature (of $27.1 K$), the gas particles undergo condensation and settle as a liquid. That's when Neon exists as a liquid.
