Question

M/6=21 What is the inverse operation and properties of equality to isolate the variable.

Answer 1

Since you are dividing here, the inverse operation would be multiplication. But I can't say I'm sure about the Properties Of Equalities part. None of them really support this equation.

Answer 2

Answer: The inverse operation is multiplication and the property of equality is called multiplication property of equality.

Step-by-step explanation: To isolate the variable, we have to multiply both sides of the equality by 6. This is a property of equality, i.e. logical rules that allow you the manipulate equations.

In this particular equation, we use multiplication property of equality, which states you can multiply both sides of an equation by the same number, other than 0, and the operation won't change the equality:

$\frac{m}{6} = 21$

$6.\frac{m}{6} = 21.6$

m = 126
