Equation:

8 - 3 * x = 2 → we solve for 3 * x

8 - 3x = 2 → we take 8 to the right side of the equation

-3x = 2 - 8 → we solve for 2 - 8

-3x = -6 → we take -3 to the right side of the equation

x = -6 / -3 → we solve for -6 / -3

x = 2 → final answer


Proof:

8 - 3 * 2 = 2 → we solve for 3 * 2

8 - 6 = 2 → we solve for 8 - 6

2 = 2 → numbers are the same, meaning our equation is correct


Answer:

[tex]\boxed{\bf~x~=~2}[/tex]
