You can put this solution on YOUR website! First, we want to get rid of the fractions in the equation.
We can do this by multiplying by the least common denominator, which is 45. (x/9)*45+(2x/5)*45=3
5x+18x=3*45
Then, we can combine our x's and multiply the two numbers in the second half of the equation.
23x=135
Finally, we can divide both sides by 23 to isolate the variable.
x=5.869565217...
We can round this number to 5.87.
So, x is about 5.87.
