Just solve the equation 4.72(x-6.56)=10.4 The first step is to reverse the multiplication by adding 4.72 after dividing by 4.72 what number should be added to both sides?
To reverse the multiplication by adding 4.72, we divide both sides of the equation by 4.72:
4.72(x - 6.56) = 10.4
(x - 6.56) = 10.4 / 4.72
To find the number that should be added to both sides, we first simplify the right side by dividing 10.4 by 4.72:
10.4 / 4.72 ≈ 2.203
(x - 6.56) = 2.203
Now, we need to isolate the variable x. To remove the negative 6.56 from the left side, we add 6.56 to both sides of the equation:
(x - 6.56) + 6.56 = 2.203 + 6.56
x = 8.763
Therefore, the number that should be added to both sides is 6.56.
