Let's solve this equation and put the words with it along the way.
1) 7x = 2(x - 5) [given: this is, well, the problem]
2) 7x = 2x - 10 [Distributive Property: 2 was distributed throughout (x-5)]
3) 5x = -10 [Subtraction Property of Equality: We subtracted 2x on both sides]
4) x = -2 [Division Property of Equality: We divided both sides by 5]
Hope this helps!

Answer: x>5
Step-by-step explanation: The Absolute Value term is |4x+6|
For the Negative case, we'll use -(4x+6)
For the Positive case, we'll use (4x+6)
-(4x+6) = 14
Multiply
-4x-6 = 14
Rearrange and Add up
-4x = 20
Divide both sides by 4
-x = 5
Multiply both sides by (-1)
x = -5
Which is the solution for the Negative Case
(4x+6) = 14
Rearrange and Add up
4x = 8
Divide both sides by 4
x = 2
x=-5
x=2
