To determine if Keith's guess of 8 is correct for the equation "? 2 = 4", we need to solve the equation.
If we denote the unknown number as "x", the equation can be rewritten as:
x * 2 = 4 (assuming "?" represents multiplication)
To solve for x, we divide both sides by 2:
x = 4 / 2 x = 2
Since Keith guessed 8 and the correct solution is 2, Keith does not have the correct solution.
So the answer is No.
