Question

3/4x + 4/7y = 5/4x -1...solve for y​

Answer 1

`(3)/(4) x + (4)/(7) y = (5)/(4) x - 1 \\ (4)/(7) y = (5)/(4) x - 1 - (3)/(4) x \\ \\ (4)/(7) y = (5x - 4 - 3x)/(4) \\ (4)/(7) y = (2x - 4)/(4) \\ \\ y = (2x - 4)/(4) / (4)/(7) \\ y = (2x - 4)/(4) * (7)/(4) \\ \\ y = (14x - 28)/(16) \\ \\ y = (14x)/(16) - (28)/(16)`
