12x+15\left(9-x\right)+10\left(9-x\right)=3\times 60+41
Multiply both sides of the equation by 60, the least common multiple of 5,4,6,60.
12x+135-15x+10\left(9-x\right)=3\times 60+41
Use the distributive property to multiply 15 by 9-x.
-3x+135+10\left(9-x\right)=3\times 60+41
Combine 12x and -15x to get -3x.
-3x+135+90-10x=3\times 60+41
Use the distributive property to multiply 10 by 9-x.
-3x+225-10x=3\times 60+41
Add 135 and 90 to get 225.
-13x+225=3\times 60+41
Combine -3x and -10x to get -13x.
-13x+225=180+41
Multiply 3 and 60 to get 180.
-13x+225=221
Add 180 and 41 to get 221.
-13x=221-225
Subtract 225 from both sides.
-13x=-4
Subtract 225 from 221 to get -4.
x=\frac{-4}{-13}
Divide both sides by -13.
x=\frac{4}{13}
Fraction \frac{-4}{-13} can be simplified to \frac{4}{13} by removing the negative sign from both the numerator and the denominator.
