Question

Given that 5 x − 8 y = 29 Find y when x = − 1 Give your answer as an improper fraction in its simplest form.

Answer 1

$\huge\mathbb{\red A \pink{N}\purple{S} \blue{W} \orange{ER}}$

5(-1) -8y = 29

-5 -8y = 29

-8y = 29 + 5

-8y = 34

y= 34/-8

y = 17/-4 = -17/4

so the ans. is 4 1/4

in improper fraction

Answer 2

Answer:

y=-34/8 or y=-17/4

Step-by-step explanation:

5x -8y=29

if x=-1 than

5(-1) -8y=29

-5 -8y=29

-8y =29+5

-8y=34

y=-34/8

is divided by 2

y=-17/4
