0.1x+0.11x+33=117
Use the distributive property to multiply 0.11 by x+300.
0.21x+33=117
Combine 0.1x and 0.11x to get 0.21x.
0.21x=117-33
Subtract 33 from both sides.
0.21x=84
Subtract 33 from 117 to get 84.
x=\frac{84}{0.21}
Divide both sides by 0.21.
x=\frac{8400}{21}
Expand \frac{84}{0.21} by multiplying both numerator and the denominator by 100.
x=400
Divide 8400 by 21 to get 400.
