Question

Solve for U


`(s - t)/(u - 8) = r`
​

Answer 1

u=
`(s)/(r) - (t)/(r) + 8`

Explanation:

Multiply each term by u-8 and simplify.

s - t = ru - 8r

Rewrite the equation as ru - 8r + s - t

add 8r to both sides of the equation.

ru + s - t + 8r

Divide each term by r and simplify

Answer 2

Multiply both sides by u-8 then divide by -8r to get s-t/-8r = u
