Given that 9 x − 4 y = 20 Find y when x = − 2 Give your answer as an improper fraction in its simplest form.

Zigmanuir [339]

Answer:

y = $-9 \frac{1}{2}$

Step-by-step explanation:

9x-4y = 20

Given that x = -2

Putting in the above equation

9(-2) -4y = 20

-18 - 4y = 20

-4y = 20+18

-4y = 38

Dividing both sides by -4

y = $-\frac{38}{4}$

y = $-\frac{19}{2}$

y = $-9 \frac{1}{2}$
