7. 4(r+3)=t, for r

Question

7. 4(r+3)=t, for r

Accepted Answer

Step:1 ：Distribute the 4 on the left side of the equation to get (4r + 12 = t).Step:2 ：Subtract 12 from both sides to isolate (r), resulting in (4r = t - 12).Step:3 ：Divide both sides by 4 to solve for (r), giving the final answer (r = boxed{frac{t}{4} - 3}).
