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
