0.75x=0.45x+1.35
Use the distributive property to multiply 0.45 by x+3.
0.75x-0.45x=1.35
Subtract 0.45x from both sides.
0.3x=1.35
Combine 0.75x and -0.45x to get 0.3x.
x=\frac{1.35}{0.3}
Divide both sides by 0.3.
x=\frac{135}{30}
Expand \frac{1.35}{0.3} by multiplying both numerator and the denominator by 100.
x=\frac{9}{2}
Reduce the fraction \frac{135}{30} to lowest terms by extracting and canceling out 15.
