Question

To solve the equation 4.72 (x - 6.56) = 10.4, the first step is to reverse the multiplication by dividing by 4.72. After dividing by 4.72, What number should be added to both sides?

Answer 1

To reverse the multiplication of 4.72, we need to divide both sides of the equation by 4.72:

4.72(x - 6.56) / 4.72 = 10.4 / 4.72

Simplifying both sides:
x - 6.56 = 2.203

To isolate the variable x, we can add 6.56 to both sides of the equation:

x - 6.56 + 6.56 = 2.203 + 6.56

Simplifying:
x = 8.763

So the number that should be added to both sides is 6.56.
