Question

Given that 5x-4y=34 find y when x =-3 give your answer in an improper fraction

Answer 1

y = -
`(49)/(4)`

Explanation:

Given

5x - 4y = 34 ← substitute x = - 3 into the equation

5(- 3) - 4y = 34

- 15 - 4y = 34 ( add 15 to both sides )

- 4y = 49 ( divide both sides by - 4 )

y = -
`(49)/(4)`
