The numerical value of x that makes the equation 4x + 12 = 8x - 2 true is x = 3.5.
Given the equation in the question:
4x + 12 = 8x - 2
To solve for the value of x that makes the equation 4x + 12 = 8x - 2 true, we simply solve for x:
4x + 12 = 8x - 2
Collect the terms with the variables on one side of the equation and the constant terms on the other side of the equation:
Firstly, subtract 4x from both sides:
4x - 4x + 12 = 8x - 4x - 2
0 + 12 = 8x - 4x - 2
Add 2 to both sides of the equation:
0 + 12 + 2 = 8x - 4x - 2 + 2
12 + 2 = 8x - 4x
14 = 4x
4x = 14
Divide both sides by 4:
x = 14/4
x = 3.5
Therefore, the value of x is 3.5
