Determine the value of rm In the given equation.
1000-n=258 Write the equation
1000-n-1000=258-1000 Subtract 1000 from both sides
-n=-742 Simplify
$$\displaystyle-{1}\frac{n}{{1}}=-\frac{742}{ -{{1}}}$$ Divide both sides by -1
n=742 Simplify
Check by substituting the value of n to the original equation.
1000-n=258 Write the equation
1000-742=258 Substitute the value of m
258 =258 This statement is true
