Answer:

  1. [tex]\huge{x = - \frac{5}{4} + \frac{7}{4} y}[/tex]
  2. [tex]\huge{x = - \frac{7}{3} + \frac{2}{3} y}[/tex]

Step-by-step explanation:

1. [tex]4x - 7y = - 5[/tex]

[tex]4x = - 5 + 7y[/tex]

[tex]\boxed{\green{x = - \frac{5}{4} + \frac{7}{4} y}}[/tex]

[tex]y E R[/tex]

○○•○○

2. [tex]3x - 2y = - 7[/tex]

[tex]3x = - 7 + 2y[/tex]

[tex]\boxed{\green{x = - \frac{7}{3} + \frac{2}{3} y}}[/tex]

[tex]y E R[/tex]
