Answer: x=30

Step-by-step explanation:

set 4x=5x-30

subtract 5x from both sides

-x=-30 then divide both sides by -x which will end up being x=30

you can also do it the other way around

x=-30
since its vertical there equal to one another.
4x =5x +30
bring the 5 over which is -1x
-1x divided by 30 is -30
