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 undo the multiplication by 4.72, we need to divide both sides of the equation by 4.72.

Dividing both sides of the equation by 4.72, we get:

(x - 6.56) = 10.4 / 4.72

Simplifying the right side of the equation, we have:

(x - 6.56) ≈ 2.203

To isolate x, we need to get rid of the -6.56 on the left side of the equation. To do this, we add 6.56 to both sides:

(x - 6.56) + 6.56 ≈ 2.203 + 6.56

Simplifying both sides, we have:

x ≈ 8.763

Therefore, the number that should be added to both sides after dividing by 4.72 is 6.56.
