Determine the value of rm In the given equation.
$$1,000 — m = 408$$ Write the equation
$$1,000—m— 1,000 = 408—1,000$$ Subtract 1,000 from both sides
$$-m = -592$$ Simplify
$$-\frac{1m}{-1}=-\frac{592}{-1}$$ Divide both sides by -1
$$m = 592$$ Simplify
Check by substituting the value of m to the original equation.
$$1,000 -m = 408$$ Write the equation
$$1,000 -592 = 408$$ Substitute the value of m
$$408 = 408$$ The statement is true
