y=%285%2F3%29x-5
Plug in 3 into y.
3=%285%2F3%29x-5
I suppose you are trying to find x. To find x, we must isolate it one one side (solve for x.)
First, add 5 to both sides.
8=%285%2F3%29x
Then, divide 5%2F3 from both sides -- or, as we know when we divide by fractions, we can multiply instead by its reciprocal. (A reciprocal is basically the fraction flipped over -- in this case, it would be 3%2F5. Thus, we would be multiplying 3%2F5 to 8.)
8 times 3%2F5 = 4.8
ANSWER: 4.8=x or x=4.8.
