What is the solution for \( 5 - 2x = 12 \)?

5-2x=12 -2x=12-5 -2x=7 (multiplying by -1) 2x=-7 x= -7/2 = -3,5

The **value **of the **variable **x is -3.5.
To solve the equation 5 - 2x = 12, we want to isolate the **variable **x on one side of the equation.
First, we can subtract 5 from both sides of the equation :
5 - 5 - 2x = 12 - 5
Simplifying:
-2x = 7
Next, we can divide both sides of the **equation **by -2 to solve for x:
(-2x) / -2 = 7 / -2
Simplifying:
x = -7/2
Therefore, the **solution **to the equation 5 - 2x = 12 is x = -7/2, which is equivalent to x = -3.5.
