Answer
The value of x is 13.
Step-by-step explanation
We need to find the value of x.
6.6 (x + 4) = 5.1 (2x - 4)
We first open the brackets
6.6x + 26.4 = 10.2x - 20.4
We then bring the terms with x to one side and the terms without x to the other side
6.6x - 10.2x = -20.4 - 26.4
-3.6x = -46.8
Divide both sides by -3.6
(-3.6x/-3.6) = (-46.8/-3.6)
x = 13
Hope this Helps!!!
