Answer

The solution to the equation 2(4−2r)=−2(r+5) is r=9.

Steps

Step 1 ：Expand the brackets on both sides of the equation to get 8−4r=−2r−10.

Step 2 ：Move all terms involving 'r' to one side of the equation and the constant terms to the other side to get 2r=18.

Step 3 ：Divide both sides of the equation by the coefficient of 'r' to solve for 'r', giving r=9.

Step 4 ：The solution to the equation 2(4−2r)=−2(r+5) is r=9.
