Question

Solve these simultaneous equations.
4x – 7y = – 5
3x – 2y = – 7
Solution: x=

Answer 1

1. 
   `\huge{x = - (5)/(4) + (7)/(4) y}`
2. 
   `\huge{x = - (7)/(3) + (2)/(3) y}`

Explanation:

1.
`4x - 7y = - 5`

`4x = - 5 + 7y`

`\boxed{\green{x = - (5)/(4) + (7)/(4) y}}`

`y E R`

2.
`3x - 2y = - 7`

`3x = - 7 + 2y`

`\boxed{\green{x = - (7)/(3) + (2)/(3) y}}`

`y E R`
