i don’t understand where this question was but i have an example: to solve the equation r = x + h, you must find the total for r. If r = 14, the total of x+h=14. another way to say this is 14=x+h. Next we must find the variable number of h which say is 6. So the equation now is 14=x+6=? Finally we must find the variable number for X. what + 6 = 14? so now we subtract 14-6 which leaves us with 8. so the example answer is 14=8+6 or r=x+h.
