Question

Pamela is 8 years older than Jiri. The sum of their ages is 62. What is Jiri's age?

Answer 1

Jiri's age = 27

Explanation:

Let's use x for Jiri's age.

Jiri's age = x

And because Pamela is 8 years older:

Pamela's age = x + 8

Since their ages added up equal 62, the equation will be:

x + x + 8 = 62

2x + 8 = 62

2x + 8 - 8 = 62 - 8

2x = 54

2x/2 = 54/2

x = 27

And because Jiri's age is x, Jiri's age will therefore be 27.

Hope this helped!

Answer 2

Jiri is 27 years old.

Explanation:

Step 1: Declare variables

• Let Jiri’s age be
  `\displaystyle x` years old.

Since Pamela is 8 years older than Jiri. Then, Pamela’s age is
`\displaystyle{8+x}` years old.

Step 2: Form an equation

The sum of their ages together equals to 62. Therefore, we can express in mathematics/equation of
`\displaystyle{x+8+x=62}` (sum of Jiri’s age and Pamela’s).

Step 3: Solve for x-term - add like terms (x-term)

`\displaystyle{2x+8=62}`

Step 4: Subtract both sides by 8

`\displaystyle{2x+8-8=62-8}\\\\\displaystyle{2x=54}`

Step 5: Divide both sides by 2

`\displaystyle{(2x)/(2)=(54)/(2)}\\\\\displaystyle{x=27}`

Since Jiri’s age is defined as
`x` years old. Therefore, Jiri’s age is 27 years old.
