How do you solve #r-5=10#?

Answer 1

Nathan Axel

See a solution process below:

Add #color(red)(5)# to each side of the equation to solve for #r# while keeping the equation balanced:

#r - 5 + color(red)(5) = 10 + color(red)(5)#

#r - 0 = 15#

#r = 15#

To solve the equation r - 5 = 10, you can add 5 to both sides of the equation to isolate the variable r. This results in r = 15.
