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
