Decide whether the given number is a solution of the given equation. See Example 7.

EXAMPLE 7 Decide whether 2 is a solution of 3x + 10 = 8x.

Solution Replace x with 2 and see if a true statement results.

Since we arrived at a true statement after replacing x with 2 and simplifying both sides of the equation, 2 is a solution of the equation.
