Answer 3

Try each value in the equation and see which one works.

Answer 4

3r = 18 +16
add 16 on both sides
then when u get value divide it with 3 on both sides

Answer 5

3r - 6 = 18 means 3 times a number minus 6 equals 6.
Try each number in the choices.
3 times the number. Then subtract 6.
The one that equals 18 is the correct choice.
