Answer:

Let's solve your equation step-by-step.

d−10−2d+7=8+d−10−3d

Step 1: Simplify both sides of the equation.

d−10−2d+7=8+d−10−3d

d+−10+−2d+7=8+d+−10+−3d

(d+−2d)+(−10+7)=(d+−3d)+(8+−10)(Combine Like Terms)

−d+−3=−2d+−2

−d−3=−2d−2

Step 2: Add 2d to both sides.

−d−3+2d=−2d−2+2d

d−3=−2

Step 3: Add 3 to both sides.

d−3+3=−2+3

d=1
