it appears you are looking for x. 1.4+2/5x=3/15x-.08
you have to isolate the x first add .08 to both sides 1.48+2/5=3/15x i would now find the equivalence fraction of 2/5 with the denominator of 15. To do this you have to multiply 5 by 3 to get 15 so, you multiply the original numerator to get the equivalent one. 2(3)=6 1.48+6/15x=3/15x now i am going to subtract 6/15x from both sides 1.48= -3/15x to get rid of the fraction i am going to convert it to a decimal. -3/15= -.2
