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 divided by?

To reverse the multiplication of 6.24 and (x + 5.9), we can divide both sides of the equation by 6.24.

To reverse the multiplication in the equation 6.24(x + 5.9) = 20.22, you need to divide both sides of the equation by 6.24. Dividing by 6.24 will eliminate the multiplication by 6.24 on the left side of the equation.

So, both sides should be divided by 6.24.

To reverse the multiplication in the equation 6.24(x + 5.9) = 20.22, the first step is to divide both sides of the equation by 6.24.

When dividing both sides by a number, the goal is to isolate the variable on one side of the equation.

So, in this case, to isolate the variable (x + 5.9), divide both sides by 6.24:

(6.24(x + 5.9))/6.24 = 20.22/6.24

Simplifying, we can cancel out the 6.24 on the left side:

(x + 5.9) = 20.22/6.24

Now we have isolated the expression (x + 5.9) on the left side of the equation.

To solve for x, the next step is to subtract 5.9 from both sides of the equation:

(x + 5.9) - 5.9 = (20.22/6.24) - 5.9

Simplifying further:

x = (20.22/6.24) - 5.9

Now, you can calculate the right side of the equation to find the value of x.
