Answer:

[tex]\displaystyle a=\frac{d-3b}{2}[/tex]

Step-by-step explanation:

Equation Solving

It's given the formula:

d = 2a + 3b

To make a the subject, we must perform some operations to isolate the letter on the left side of the equation.

First, swap both sides:

2a + 3b = d

Subtract 3b:

2a = d - 3b

Divide by 2:

[tex]\mathbf{\displaystyle a=\frac{d-3b}{2}}[/tex]

Now a is the subject.
