0.45x+0.72+5x=18
Use the distributive property to multiply 0.45 by x+1.6.
5.45x+0.72=18
Combine 0.45x and 5x to get 5.45x.
5.45x=18-0.72
Subtract 0.72 from both sides.
5.45x=17.28
Subtract 0.72 from 18 to get 17.28.
x=\frac{17.28}{5.45}
Divide both sides by 5.45.
x=\frac{1728}{545}
Expand \frac{17.28}{5.45} by multiplying both numerator and the denominator by 100.
