    First subtract 21 from each side then you get 4+6x=4x then you subtract 6x from each side and get 4=-2x lastly you divide -2 from both sides your answer will be -2=x

    Answer:

    x=-2

    Step-by-step explanation:

    25+6x=21+4x

    Step 1: Simplify both sides of the equation.

    6x+25=4x+21

    Step 2: Subtract 4x from both sides.

    6x+25−4x=4x+21−4x

    2x+25=21

    Step 3: Subtract 25 from both sides.

    2x+25−25=21−25

    2x=−4

    Step 4: Divide both sides by 2.

    x=−2
