Answer

True

Work Step by Step

In order for a number to be a solution to an equation, it must create a true statement when plugged into the equation. For example, $5$ is a solution to the equation $x-3=2$, because when we plug in $5$, the following occurs: $$5-3=2$$$$2=2$$ Since $2$ is equal to $2$, a true statement is formed by plugging in $5$ into an equation that it is a solution to.
