Distribute the -3 to both 2n and 1 (inside the parenthesis)

-3 x 2n = -6n
-3 x 1 = -3

-6n - 3 + 7 = 5

simplify

-6n + 4 = 5

isolate the n

-6n + 4 (-4) = 5 (-4)

-6n = 1

-6n(/-6) = 1(/-6)

n = -1/6

hope this helps

Pamela is 7 years younger than Jiri. The sum of their ages is 39. What is Jiri ‘s age?
astraxan [27]

Based on the task given, Pamela's age and juri's age is 16 and 23 years respectively.

<h3>Equation</h3>

  • Juri's age = x
  • Pamela's age = x - 7
  • Their total age = 39

x + (x - 7) = 39

x + x - 7 = 39

2x = 39 + 7

2x = 46

x = 46/2

x = 23

Therefore,

Juri's age = x

= 23 years

Pamela's age = x - 7

23 - 7

= 16 years
