Question

what is the solution to the rational equation 4x/3 - 1/3 =5

Answer 1

is it this problem: \(\large \frac{4x}{3}-\frac{1}{3}=5 \)

if yes, notice the fractions already have common denominators. can you combine them as 1 fraction on the left side?

Answer 2

4X-1=15
X=4

Answer 3

@dpaInc yeah thats the problem

so would it be (4x-1)/3 = 5
(4x-1) = 15 (if you multiply both sides by 3)
then 4x= 16 (adding the -1)
then divide by 4 & get x=4?

Answer 4

I was thinking multiply both sides by 5 but I don't think that right

Answer 5

i think its 4. that seems to make sense. i have ONE more quetion similar to this one ...

Answer 6

good work...
and as u can see there are other ways of doing it but ultimately you'll get the same answer...:)

Answer 7

4x/3-1/3=5
take LCM
4x-1
----- =5
3
4x-1=5*3
4x-1=15
4x=15+1
4x=16
x=16/4
x=4
hope you understand :)

Answer 8

thanks guys :) i understand that one :)

heres the other one thats confusing:
simplify 1/x + 2/9 = 1/3

i cant get it because it doesnt have a common denominator like the other one did
