Answer:
1.x=-4+ y/2 - z/2
2. X=-4-y-z
3. x=y/3-2/3
Step-by-step explanation:
10minutes= 10/60 hours
= 1/6 hrs
speed = distance/ time
=3/ (1/6)
= 18 km/h

Answer:
84 and 8
Step-by-step explanation:
the first number will be x and the second number y.
x = 11y - 4
x + y = 92
replace x in the second equation with 11y - 4:
11y - 4 + y = 92
add 4 to each side: 11y + y = 96
simplify: 12y = 96
divide each side by 12: y = 8
now replace y in the second equation with 8:
x + 8 = 92
subtract 8 from each side: x = 84
