Their ages: x+5+x = 39 => 2x+5 = 39 => 2x = 39-5 => 2x = 34 => x = 17
Therefore: Mary is 17+5 = 22 years and Bob is 17 years
Let's denote Jasmine's age as J. Since Miguel is four years older than Jasmine, his age can be represented as J + 4. The sum of their ages is 28, so we can form the equation J + (J + 4) = 28. Simplifying this equation, we get 2J + 4 = 28. Solving for J, we find that Jasmine is 12 years old.
it depends what kind it is. if you give me an example i might solve one. Joe is 10 years older than James. In 8 years, twice Joe's age will equal three times James's age. How old is each now? Answer: Joe: 3 units James: 2 units 1units=10 years 3units=30 yea
use an equation x=sue x+x+6+x+11=41 -17 -17 3x= 24 /3 /3 x= 8 sue is 8
Let L be the age of Leah, J as the age of John, and S as the age of Sue.Equation 1: S = L - 6Equation 2: J = L + 5Equation 3: L + J = 41Using Equation 3 to get Leah's age:L + J = 41L + (L + 5) = 412L = 41 - 5L = 18Using Equation 2 and substituting L to get John's age:J = L + 5J = 18 + 5J = 23Check using Equation 3, substituting L and J:L + J = 4118 + 23 = 41Using Equation 1 , substituting L to get Sue's age.S = L - 6S = 18 - 6S = 12Sue is 12 years old.Leah is 18 years old.John is 23 years old.
In 27.5 years. [By the way, I think you mean x+x+95=150.] Let x be the number of years in the future when the sum of their ages will be 150. In x years, the younger person will be 45+x and the older will be 50+x. The sum of their ages will be 150, and the equation to find x is given by: (45+x)+(50+x)=150 Now solve for x: (45+x)+(50+x)=150 95+2x=150 2x=150-95=55 x=55/2=27.5 So the sum of their ages will be 150 in 27.5 years. The younger person will be 45+27.5=72.5 and the older person will be 50+27.5=77.5.

You write an equation, and solve it. For example, assuming you are 20 years older than your daughter, then you will always be 20 years older: x = your daughter's age 3x = your age The statement that you are 20 years older than your daughter translates to: 3x = x + 20 If you solve this equation for "x", you'll have your daughter's age. Then you can just multiply this by 3 to have your own age. Let p = the parent's date of birth, let d = the daughter's date of birth, and let z = the date when the daughter's age is 1/3 the parent's age. z = d + (d - p) ÷ 2 z = 1.5d - 0.5p Microsoft Excel or a similar spreadsheet program is excellent for performing mathematical functions on dates.
Use a convenient variable, such as "x", for her age. Then, 3 years ago her age was x-3, in three years, her age will be x+3. Write an equation with this data:x = 3(x+3) - 3(x-3)And solve it:x = 3x + 9 - 3x + 9x = 18Use a convenient variable, such as "x", for her age.

Write an equation for this:age + 4 = y - 5 = current_ageage = y - 5 - 4age = y - 94 years ago John was 9 years younger than he will be in 5 years when he is y years old. Sorry if this isn't much help but trying to solve an equation with 2 variables doesn't give definite numerical answers without additional information (which you did not provide).

I’m sorry this question dose not make sense please recheck the grammer
Without knowing which is older, you cannot assign their ages. But one is 10 and the other is 5. The idea here is to write two equations, one for the sum of the ages (B + E = 15), one for the difference. Then, solve both equations simultaneously. There are several ways to do this; for example, you can solve one of the equations for "B", and replace that variable in the other equation. x + y = 15 x = y +5 (y+5) + y = 15 2y + 5 = 15 2y = 10 y = 5 (the younger child), x = y+5 = 10 (the older child).
For this question we can say Nita = N and Joe = J and set up an equation:equation 1: N = J + 10 and equation 2: 20 = J + Nwe can solve for J using equation 1 inside of equation 2:20 = (J + 10) + J20 - 10 = 2*JTherefore: J = (20 - 10)/2 = 5Now we solve for N by plugging in 5 for J in equation 1:N = 5 + 10 = 15Nita is 15 and Joe is 5
Pete the pilot is 35 years old. His son is 9 years old. In how many years will Pete be exactly three times older than his son
Let's represent Aaron's current age as A and Julie's current age as J. Given that Julie is 4 times older than Aaron, we can write J = 4A. In ten years, Julie will be J + 10 years old and Aaron will be A + 10 years old. According to the second statement, in ten years Julie will be twice as old as Aaron, so we have J + 10 = 2(A + 10). By substituting J = 4A into this equation, we get 4A + 10 = 2A + 20. Solving this equation, we find that Aaron is 10 years old and Julie is 40 years old.
growing older
Of course! That's a great thing to do, so when you get older you look in your journal and see what happend in your childhood.
