Someone help me please?! Math problem!!!
Gala2k [10]

Answer:

y  = 4/5x  - 9/5

Step-by-step explanation:

4x - 5y = 9  to solve for y you get it by itself.

-4x          -4x   minus 4x from both sides

-5y  = - 4x + 9

/-5            /-5   Divide both sides by 5

 y  = 4/5x  - 9/5   because -4/-5 is 4/5 and 9/-5 is - 9/5
