Can you explain how to solve t=an+b (solve for b)

Question

Solve each equation for the indicated variable 

Answer 1

The equation is already solved for the variable t

 

To solve for any other variable simply rearrange the

equation to have the indicated variable on one side

of the equals sign and everything else on the other.

 

For example, to solve for a:

 

t=an+b       subtract b from both sides

t-b = an      divide both sides by n

(t-b)/n = a

 

Or:  a = (t-b)/n

 

Work in the same manner to solve for either b or n:

 

b = t-an

 

n = (t-b)/a
