Wale was twice as old as Ajay 10 years back. How old is Ajay today if Wale will be 40 years old 10. years hence?​
vagabundo [1.1K]

Using a system of equations, it is found that Ajay is 25 years old today.

<h3>What is a system of equations?</h3>

A system of equations is when two or more variables are related, and equations are built to find the values of each variable.

In this problem, the variables are:

  • Variable x: Wale's age.
  • Variable y: Ajay's age.

Wale was twice as old as Ajay 10 years back, hence:

x - 10 = 2(y - 10)

x - 10 = 2y - 20

x = 2y - 10

Wale will be 40 years old in 10 years, hence:

x + 10 = 40

x = 40

Then, Ajay's present age is found as follows.

2y = x + 10

2y = 40 + 10

y = \frac{50}{2}

y = 25

The table shows the number of students in a class who play on a school team and/or are members of a school club:
eimsori [14]
This one is very simple.

create a simple equation to find out

15 = 12 + x

subtract 12 from each side

x= 3

the missing number is 3

or, to be even simpler, take the total, subtract the total from the number you know and the difference is the missing number.

hope I helped



ALSO, we can check going down vertically. 3 + 10 =13. this is the total listed at the bottom.

Help Please solve this picture
Drupady [299]

6y = (x - 4)² + 34/3

6x = (y - 4)² + 34/3

(y - 4)² = 6x - 34/3

y - 4 = √(6x - 34/3)

y = 4 +- √(6x - 34/3)
