Whats 42=-2d+6 answer?

-2d+6=42

ok first you will take 6 and subtract it from 6 and take 42 and subtract 6

-2d+6-6=42-6

-2d=36

Now you divide - 2/-2 and 36/-2

d=-18

because positive and a negative divided is a negative

42=-2d+6

Flip the equation.

-2d+6=42

Subtract 6 from both sides.

-2d+6-6=42-6

-2d=36

Divide both sides by - 2.

-2d/-2 = 36/-2

d=-18
