Question

Solve the formula a(m - r) + t = s for a

Answer 1

`\huge\boxed{a =(s-t)/(m-r)}`

Explanation:

In order to convert an equation to solve for another variable, we need to algebraically manipulate the problem until we're left with a isolated on one side.

Step 1: Subtract
`t` from both sides

• 
  `a(m-r) + t - t = s - t`
• 
  `a(m-r) = s-t`

Step 2: Divide both sides by
`m- r`

• 
  `(a(m-r))/(m-r) = (s-t)/(m- r)`
• 
  `a = (s-t)/(m-r)`
