Find the Value of r,if 5(r-3)=20

Answer 1

To find the value of r, we can solve the equation 5(r-3) = 20.

First, we distribute the 5 to both terms inside the parentheses:
5r - 15 = 20

Next, we can add 15 to both sides of the equation to isolate the variable term:
5r = 35

Finally, we can divide both sides of the equation by 5 to solve for r:
r = 7

Therefore, the value of r is 7.
