The equation "0 = 2X + 4" is a linear equation in one variable, where X represents an unknown value. To solve for X, we can rearrange the equation by isolating X on one side. This involves moving the constant term, 4, to the other side, resulting in "2X = -4." Next, we divide both sides of the equation by 2 to find the value of X. This gives us "X = -2." Thus, the solution indicates that when X equals -2, the equation holds true, meaning that substituting -2 back into the original equation will yield a true statement.
