Solve for x if 5x/3 + 4 = 3x-2/5
Answer is 33/10
this is an easy problem but i can't solve it-maybe i've been studying too much 🙂 thanks.

i know the answer is 33/10 b/c i got it from the answer key, but what is the set up of the problem to arrive at the answer?

Here's how i did it:

5x/3 + 4 = 3x-2/5

4+2/5 = 3x - (5x/3)

(20/5) +(2/5) = (9x/3) - (5x/3)

22/5 = 4x/3

x = (22x3)/(5x4) = 33/10

Here's how i did it:

5x/3 + 4 = 3x-2/5

4+2/5 = 3x - (5x/3)

(20/5) +(2/5) = (9x/3) - (5x/3)

22/5 = 4x/3

x = (22x3)/(5x4) = 33/10

thanks
