2\left(5x+4\right)+12=9x
Multiply both sides of the equation by 4, the least common multiple of 2,4.
10x+8+12=9x
Use the distributive property to multiply 2 by 5x+4.
10x+20=9x
Add 8 and 12 to get 20.
10x+20-9x=0
Subtract 9x from both sides.
x+20=0
Combine 10x and -9x to get x.
x=-20
Subtract 20 from both sides. Anything subtracted from zero gives its negation.
