Simplifying
1.5d + 3.25 = 1 + 2.25d

Reorder the terms:
3.25 + 1.5d = 1 + 2.25d

Solving
3.25 + 1.5d = 1 + 2.25d

Solving for variable 'd'.

Move all terms containing d to the left, all other terms to the right.

Add '-2.25d' to each side of the equation.
3.25 + 1.5d + -2.25d = 1 + 2.25d + -2.25d

Combine like terms: 1.5d + -2.25d = -0.75d
3.25 + -0.75d = 1 + 2.25d + -2.25d

Combine like terms: 2.25d + -2.25d = 0.00
3.25 + -0.75d = 1 + 0.00
3.25 + -0.75d = 1

Add '-3.25' to each side of the equation.
3.25 + -3.25 + -0.75d = 1 + -3.25

Combine like terms: 3.25 + -3.25 = 0.00
0.00 + -0.75d = 1 + -3.25
-0.75d = 1 + -3.25

Combine like terms: 1 + -3.25 = -2.25
-0.75d = -2.25

Divide each side by '-0.75'.
d = 3

Simplifying
d = 3

First off you need to get all letters on on the left side of the equal sign, you will do this by subtracting 2.25 from the right and that would give you -0.75d+3.25=1 now you will subtract 3.25 from the right side and get -.75d=-2.25. And lastly you divide both sides by -0.75 and that will give you d= 3
