Answer:
Explanation:
To solve for r, we need to isolate the variable r on one side of the equation.
1/4r - 4 = 20
First, we'll add 4 to both sides of the equation:
1/4r - 4 + 4 = 20 + 4
Simplifying:
1/4r = 24
Next, we'll multiply both sides of the equation by 4 to eliminate the fraction:
1/4r * 4 = 24 * 4
Simplifying:
r = 96
Therefore, the solution to the equation 1/4r - 4 = 20 is r = 96.
