\left(5-1\right)d
Subtract the numbers
4d
4d-7
4d-7+4=0
Add the numbers
4d-3=0
Move the constant to the right-hand side and change its sign
4d=0+3
Removing 0 doesn't change the value,so remove it from the expression
4d=3
Divide both sides
\frac{4d}{4}=\frac{3}{4}
Solution
d=\frac{3}{4}
Alternative Form
d=0.75
