15\left(3x-0,4\right)+10\left(1,5-2x\right)=6\left(x+6,5\right)
Multiply both sides of the equation by 30, the least common multiple of 2;3;5.
45x-6+10\left(1,5-2x\right)=6\left(x+6,5\right)
Use the distributive property to multiply 15 by 3x-0,4.
45x-6+15-20x=6\left(x+6,5\right)
Use the distributive property to multiply 10 by 1,5-2x.
45x+9-20x=6\left(x+6,5\right)
Add -6 and 15 to get 9.
25x+9=6\left(x+6,5\right)
Combine 45x and -20x to get 25x.
25x+9=6x+39
Use the distributive property to multiply 6 by x+6,5.
25x+9-6x=39
Subtract 6x from both sides.
19x+9=39
Combine 25x and -6x to get 19x.
19x=39-9
Subtract 9 from both sides.
19x=30
Subtract 9 from 39 to get 30.
x=\frac{30}{19}
Divide both sides by 19.
