Answer:
x > 1
interval (1,∞)
Step-by-step explanation:
1/2(-2x - 12) > 7(3 - 4x)
-x - 6 > 21 - 28x
-x + 28x > 21 + 6
27 x > 27
x > 27 / 27
x > 1
interval (1,∞)
-x - 6 > 21 - 28x if x = 2
-2 - 6 > 21 -28(2)
-8 > 21 - 56
- 8 > - 35
Answer:
x=13.6
Step-by-step explanation:
First, let's distribute.
7x-21=4x+20
Second, let's subtract 4x from both sides.
3x-21=20
Next, let's add 21 to both sides.
3x=41
Lastly, let's divide 3 from both sides.
x=13.66666667
x=13.6
