Answer:
r=37
Step-by-step explanation:
r−14=23
Add 14 to both sides.
r−14+14=23+14
R = 37
First you want to get R by it self so your going to move -14 to the other side. When you move it over you make it the opposite of what it was so the -14 turns into a positive than add 32 and 14 together and you get 37
