Start with original equation:
42 = -2d + 6
Your main goal is to get 'd' on one side by itself. So, subtract 6 from both sides:
42 - 6 = -2d + 6 - 6
36 = -2d
Now, divide both sides by -2d.
36/-2 = -2d/-2
-18 = d
To make it easier to read:
d = -18

-2d+6=42
-2d=36
d= -18

42 = -2d+6
42-6 = -2d
36 = -2d
multiply both sides by -(1/2), then we have
-18 = d
d is -18

42 = -2d + 6
42 - 6 = -2d
36 = -2d
36/-2 = -2d/-2
-18 = d
Good luck!

42=-2d+6
2d+42=6
2d=-36
d=-18

42 = -2d + 6
-6 -------- - 6
__________
37 = 2d
36/2= 18
their you go know give me ten points

ok so 42-6 = 36...
then 36/-2 = -18
so d =-18
2007-09-11 19:55:47 · answer #8 · answered by Anonymous · 0⤊ 0⤋
if you would like to solve for d, this is very simple;
42=-2d+6
42+2d=6
2d=6-42
2d=-36
d=-18
that's it...
