    Well the answer is correct but the working out is wrong because you are supposed to subtracts 4x by both sides first then factor out x thirdly find the equation solutions and then solve

    Step 1) 3x^2 – 4x = 0
    Step 2) x(3x – 4) = 0
    Step 3) x = 0
    Step 4) 3x – 4 = 0 + 4 hereby leaves 3x = 4
    Step 5) x = 0 and x = 4/3
