Question

Rearrange the following formulae to make the letter in a the subject

d=2a+3b​

Answer 1

`\displaystyle a=(d-3b)/(2)`

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:

`\mathbf{\displaystyle a=(d-3b)/(2)}`

Now a is the subject.
