42 menit + 48 menit berapa

First, establish what you already know to be true: P = 3 + R E = 2 R R + E = 81
You can use these equations to solve each other. Let's take the last one, R + E = 81 . Using the additive property of equality, we find that R = 81 − E . We now know that Mr. Richard's age is 81 minus Mr. Edward's age. If we substitute this equation into the second one, we have E = 2 ( 81 − E ) . Now use the distributive property to simplify: E = 162 − 2 E , and solve for E : E = 162 − 2 E 3 E = 162 E = 54 .
Now we have a definite age. Use this to find the other two ages: R + 54 = 81 R = 27 and 27 = 3 + P − P + 27 = 3 − P = − 24 P = 24 . **
We now know that Ms. Pacheo is 24, Mr. Edwards is 54, and Mr. Richard's is 27! :D**

Mr edwards = Mr r x 2 Mr r = Mr p - 3 = Mr e ÷ 2. Mr p = 30 Mr e + Mr r = 81. Mr e = 54 Mr p = Mr r + 3. Mr r = 27
Mr Edwards = 2(Mr p - 3) Mr e = 2(mr p) - 6
Mr r = [2(Mr p) -6] ÷ 2 Mr r = [2( Mr r + 3) - 6] ÷ 2
2(Mr r) + (Mr p - 3) = 81 2(Mr p -3) + (Mr p - 3) = 81 3(Mr p - 3) = 81 3(Mr p) - 9 = 81. Hope this helps!!!
3(Mr p) + 9 = 81 + 9 3(Mr p) = 90 Mr p = 90 ÷ 3 Mr p = 30

Mr. Richards is 27 years old, Ms. Pacheco is 30 years old, and Mr. Edwards is 54 years old. We found these ages by setting up equations based on the relationships described in the problem. The total of Mr. Richards' and Mr. Edwards' ages equals 81, leading us to calculate their individual ages.
