0.25\times 100+0.3\times 10-x\left(100+10\right)=27.5x
Variable x cannot be equal to 0 since division by zero is not defined. Multiply both sides of the equation by x.
25+0.3\times 10-x\left(100+10\right)=27.5x
Multiply 0.25 and 100 to get 25.
25+3-x\left(100+10\right)=27.5x
Multiply 0.3 and 10 to get 3.
28-x\left(100+10\right)=27.5x
Add 25 and 3 to get 28.
28-x\times 110=27.5x
Add 100 and 10 to get 110.
28-x\times 110-27.5x=0
Subtract 27.5x from both sides.
28-110x-27.5x=0
Multiply -1 and 110 to get -110.
28-137.5x=0
Combine -110x and -27.5x to get -137.5x.
-137.5x=-28
Subtract 28 from both sides. Anything subtracted from zero gives its negation.
x=\frac{-28}{-137.5}
Divide both sides by -137.5.
x=\frac{-280}{-1375}
Expand \frac{-28}{-137.5} by multiplying both numerator and the denominator by 10.
x=\frac{56}{275}
Reduce the fraction \frac{-280}{-1375} to lowest terms by extracting and canceling out -5.
