So it's asking you to solve the equation for the letter R, but there are no values. You can still solve, however, because if you rewrite it as. D = R × T, then you can see that if you divide by T you get D ÷ T = R, which is the letter they wanted. This would be your answer, I hope this helps!
You're looking for R and Because R and T are on one side you have to move the T , to do this you have to divide T from both sides , this is because R multiples with T (RT) and the opposite of Multiplication is division . Your answer is D/T=R or D over T = R
