9\left(x-4\right)=5\left(2x+4\right)+405
Multiply both sides of the equation by 45, the least common multiple of 5,9.
9x-36=5\left(2x+4\right)+405
Use the distributive property to multiply 9 by x-4.
9x-36=10x+20+405
Use the distributive property to multiply 5 by 2x+4.
9x-36=10x+425
Add 20 and 405 to get 425.
9x-36-10x=425
Subtract 10x from both sides.
-x-36=425
Combine 9x and -10x to get -x.
-x=425+36
Add 36 to both sides.
-x=461
Add 425 and 36 to get 461.
x=-461
Multiply both sides by -1.
