Question

5-7y/2+4y equals -8/7​

Answer 1

`\boxed{y = 3}`

Explanation:

`= > (5 - 7y)/(2 + 4y) = - (8)/(7) \\ \\ = > 7(5 - 7y) = - 8(2 + 4y) \\ \\ = > (7 * 5) - (7 * 7y) = ( - 8 * 2) + ( - 8 * 4y) \\ \\ = > 35 - 49y = - 16 - 32y \\ \\ = > 35 - 49y + 32y = - 16 \\ \\ = > 35 - 17y = - 16 \\ \\ = - 17y = - 16 - 35 \\ \\ = > \cancel{- }17y = \cancel{- } 51 \\ \\ = > 17y = 51 \\ \\ = > y = (51)/(17) \\ \\ = > y = 3`
