-3x - 4y - 2z = 0
x + 3y + 2z = 1
-2x - y = 1
-4x - 4y - 2z = 10
3x + 4y +2z= 0
-x = 10. x = -10
-2(-10) - y = 1
20 - y = 1
-y = -19
y = 19
-10 + 3(19) + 2z = 1
-10 + 57 + 2z = 1
47 + 2z = 1
2z = -46
z= -23
check: 2(-10)+2(19)-23=-5
-20+38-23=-5
-43+38=-5
-5=-5

Answer:
Total = m + j
= 3 + m + 21
Step-by-step explanation:
Mails = 3 miles
Jared = 3 miles + 21 miles
j = m + 21
m = 3
Total = m + j
= 3 + m + 21
Where,
m = 3
Total = 3 + m + 21
= 3 + 3 + 21
= 27
Average of 10 people = 65
65 × 10 = 650
average of 5 people = 35
35 × 5 = 175
650 + 175 = 825
825 ÷ 15 = 55
the average reading time for the entire book club each day is 55 minutes a day
