Answer:
d=2
Step-by-step explanation:
Let's solve your equation step-by-step.
3+4.5(2d−3)=7.5
Step 1: Simplify both sides of the equation.
3+4.5(2d−3)=7.5
3+(4.5)(2d)+(4.5)(−3)=7.5(Distribute)
3+9d+−13.5=7.5
(9d)+(3+−13.5)=7.5(Combine Like Terms)
9d+−10.5=7.5
9d−10.5=7.5
Step 2: Add 10.5 to both sides.
9d−10.5+10.5=7.5+10.5
9d=18
Step 3: Divide both sides by 9.
9d
9
=
18
9
