Question

Solve for i ?

** 9x-7i>3(3x-7u) **

Answer 1

Answer:

Start by expanding the brackets on the right-hand side. This gives you

9x−7i>9x−21u

Next, subtract  9x  from both sides (the inequality now does not have an  x  in it - so we cannot solve for  x ) but leaves

−7i>−21u

If you multiply both sides by -1 (to clear negatives) then you have to reverse the inequality sign, so you get

7i<21u

You may solve for either  i  or  u, divide by 7 to get  i :

i<3u
