Question

solve for u. 19u = 7(5u - 20) - 20 u = submit

Explanation:

Step1: Expand the right-hand side

$19u = 35u - 140 - 20$

Step2: Simplify constants on RHS

$19u = 35u - 160$

Step3: Isolate u terms on one side

$19u - 35u = -160$

Step4: Combine like terms

$-16u = -160$

Step5: Solve for u by dividing

$u = \frac{-160}{-16}$

Answer:

$u = 10$
