2/3+y−4/5=1/3 by the way 2/3,4/5, and 1/3 are fractions

Luden [163]

Find the common denominator between 2/3 and 4/5 which is 15.

It will look like this:
(10-12)/15+y=1/3

Calculated:
-2/15+y=1/3

Then Add 2/15 to the other side:
Y=1/3+2/14

Again change the denominator of 1/3 to equal 15 but multiplying the whole fraction by 5.

Y= (5+2)/15
Y=7/15

You have to plug the given input in the formula: if you substitute t with 21 you have

$g(t) = \dfrac{t-6}{3} \implies t(21) = \dfrac{21-6}{3}=\dfrac{15}{3}=5$
