Answer:
29
Step-by-step explanation:
Let Jiri's age be 'x'. Pamela's age is 3x since Pamela's age is three times Jiri's age.
The sum of their ages is 116:
x + 3x = 116
4x = 116
x = 116 ÷ 4 = 29
x = 29
Jiri's age is 29
<span>A) X + y + z = 7
B) 2x − y + z = 7
C) 3x − z = 2
</span><span>C) z = 3x -2 Substituting this into equations A) and B)
</span>
<span>A) X + y + 3x -2 = 7
B) 2x − y + 3x -2 = 7 Adding A and B
3x + 6x -4 = 14
9x = 18
x = 2
</span>Since x = 2 then
<span>A) 2 + y + 6 -2 = 7
</span><span>A) y = 1
</span>A) X + y + z = 7
<span>A) 2 + 1 + z = 7</span>
z = 4
