Solve the equation, and check your solution. See Examples.

EXAMPLE Applying the Multiplication Property of Equality
Solve 5x = 60.
Substitute 12 for x in the original equation.
Since a true statement results, the solution set is {12}.
EXAMPLE Applying the Multiplication Property of Equality
Solve 25x = −30
The check confirms ms that the solution set is .
EXAMPLE Solving an Equation with Decimals
Solve – 2.1x = 6.09
Check by replacing x with – 2.9 in the original equation. The solution set is {−29}
EXAMPLE Applying the Multiplication Property of Equality
Solve
Since a true statement results, the solution set is {12}.
EXAMPLE Applying the Multiplication Property of Equality
Solve .
Check to confirm m that the solution set is {8}.
EXAMPLE Applying the Multiplication Property of Equality
Solve −x = −17
The solution, 17, checks, so {17} is the solution set.
