Question

This half my grade i cant fail help

Answer 1

Let's see what to do buddy....

`T = b + (d)/(2f) \\`

Subtract sides b

`T - b = b - b + (d)/(2f) \\`

Simplification

`T - b = (d)/(2f) \\`

Multiply sides by 2f

`(T - b)(2f) = d`

So ;

`d =( T - b) * (2f)`

We're done but i wanna go one step more...

`d = T * 2f - b * 2f`

`d = 2Tf - 2bf`
