To solve the equation 6.24 ( x + 5.9 ) = 20.22, the first step is to reverse the multiplication. What number should both sides be divide by?

Answer 1

To isolate the expression on the left side of the equation \(6.24 (x + 5.9) = 20.22\), you should divide both sides by \(6.24\).

This would give you:

\[ x + 5.9 = \frac{20.22}{6.24} \]

So, the number you should divide both sides by is \(6.24\).
