Explanation:

3 +6d+2d=24

3+8d=24

8d=21

d = 21/8

Step 4 one does not divide both sides by by 14

The incorrect step and with error is subtract 3 from both sides. Option 3

We have that the equation is;

-3/8 (-8-16d) + 2d= 24

multiply the values, we get;

-24 + 48d + 2d = 24

add the like terms

-24 + 50d = 24

50d = 48

d = 48/50

The other steps are;

Subtract 3 from both sides (However, the instruction mentions subtracting 3, but there is no number 3 in the equation.

Divide both sides by the equation by -14
