    If (a=2) (b=-3) (c=-1) and (d=4); then the first expression would be written as (2•4-2), which is equivalent to (8-2), it is also equivalent to (6); and the second expression would be written as (5•-3•-1), which is equivalent to (-15•-1), as well as (15), it ends up being positive because a negative number multiplied by a negative number equals a positive number.

    2d - a = 6

    5bc = 15

    Step-by-step explanation:

    Substitute your values into the equation

    2 (4) - 2 = 6

    5 (-3) (-1) = 15
