Question

Given that
3 x − 5 y = 15
Find y when x = 1
Give your answer as an improper fraction in its simplest form.

Answer 1

Answer:

y = - $\frac{12}{5}$

Step-by-step explanation:

Given

3x - 5y = 15 ← substitute x = 1 into the equation

3(1) - 5y = 15

3 - 5y = 15 ( subtract 3 from both sides )

- 5y = 12 ( divide both sides by - 5 )

y = - $\frac{12}{5}$
