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
Answer:
d=1.
im pretty sure
