Answer 1

`\\ \sf\longmapsto 9e-7=7e-11`

`\\ \sf\longmapsto 9e-7e=-11+7`

`\\ \sf\longmapsto 2e=-4`

`\\ \sf\longmapsto e=(-4)/(2)`

`\\ \sf\longmapsto e=-2`

Answer 2

Let's solve for e :

• 
  `9e - 7 = 7e - 11`

• 
  `9e - 7e = - 11 + 7`

• 
  `2e = - 4`

• 
  `e = - 4 / 2`

• 
  `e = - 2`

value of " e " = -2
