Ответ:
1. Option B- y=12
2. Option D - 2
Step-by-step explanation:
1. 2(y - 4) + 8 = 12 + y
2y - 8 + 8 = 12 + y
add like terms -8 + 8 is 0 so
2y = 12 + y
Subtract y
1y = 12
Divide by 1
y= 12
2. -4(2) - 6 > -14
-8 - 6 > -14
-14 > -14
This is not true because -14 is not greater than -14, they are equal.
Hope this helps.
