Question

−11=3d+6d−2 sove for D

Answer 1

Answer:

d=-1

Step-by-step explanation:

1st Switch sides: 3d+6d-2=-11

2nd Add similar elements: 3d+6d=9d

            9d-2=-11

3rd Add 2 to both sides: 9d-2+2=-11+2

4th Simplify: 9d=-9

5th Divide both sides by 9: 9d÷9=-9÷9

6th Simplify d=-1

Answer 2

Answer: -1

Step-by-step explanation: 3d+6d−2=−11

3d+6d−2=−11

Step 1: Simplify both sides of the equation.

3d+6d−2=−11

3d+6d+−2=−11

(3d+6d)+(−2)=−11(Combine Like Terms)

9d+−2=−11

9d−2=−11

Step 2: Add 2 to both sides.

9d−2+2=−11+2

9d=−9

Step 3: Divide both sides by 9.

9d/9 -9/9d

d=-1 sorry if its hard to understand
