9\times 5-6\left(5x+5\right)=10\left(-x+25\right)
Multiply both sides of the equation by 90, the least common multiple of 10,15,45.
45-6\left(5x+5\right)=10\left(-x+25\right)
Multiply 9 and 5 to get 45.
45-30x-30=10\left(-x+25\right)
Use the distributive property to multiply -6 by 5x+5.
15-30x=10\left(-x+25\right)
Subtract 30 from 45 to get 15.
15-30x=10\left(-x\right)+250
Use the distributive property to multiply 10 by -x+25.
15-30x-10\left(-x\right)=250
Subtract 10\left(-x\right) from both sides.
15-30x-10\left(-1\right)x=250
Multiply -1 and 10 to get -10.
15-30x+10x=250
Multiply -10 and -1 to get 10.
15-20x=250
Combine -30x and 10x to get -20x.
-20x=250-15
Subtract 15 from both sides.
-20x=235
Subtract 15 from 250 to get 235.
x=\frac{235}{-20}
Divide both sides by -20.
x=-\frac{47}{4}
Reduce the fraction \frac{235}{-20} to lowest terms by extracting and canceling out 5.
