    Answer:

    -19^{\circ}

    Step-by-step explanation:

    Let x represent temperature on 4th day.

    We have been given that the temperatures was recorded for the first three days were -2°,10°,and 7°.

    The total temperature on f days would be -2^{\circ}+10^{\circ}+7^{\circ}+x.

    We have been given that total temperature change was -4°. We can represent this information in an equation as:

    -2^{\circ}+10^{\circ}+7^{\circ}+x=-4^{\circ}

    15^{\circ}+x=-4^{\circ}

    x=-4^{\circ}-15^{\circ}

    x=-19^{\circ}

    Therefore, the temperature on 4th day must be equal to -19^{\circ}.
