Answer:
The number is -6.
Step-by-step explanation:
Variable x = a number
Set up an equation:
3x + 12 = -6
Isolate variable x:
3x = -18
x = -6
Check your work:
3(-6) + 12 = -6
-18 + 12 = -6
-6 = -6
Correct!
3x +12=-6
3x=-6-12
3x=-18
x=-18/3
x=-6
D: 4(2a+3)=8a+3
4x2a = 8a and 4x3 = 12
angle v and angle w,
angle x and angle y
