    Answer:

    21x – 4

    Step-by-step explanation:

    7(2 – 3x) – 10

    Multiply 7 with the numbers in the parentheses.

    14 – 21x – 10

    Add/subtract like terms.

    4 – 21x

    Rearrange expression from highest degree to lowest. (In this case 21x has a degree if 1, 4 has 0)

    21x – 4
