A. x = -7 and x = -15
B. x = 7 and x = -7
C. x = -7 and x = 15
D. x = 7 and x = -15

Answer :

Option:-

  • [tex] \underline{\sf \color{brown}{ B ) x = 7 nd \: x = -7}}[/tex]

[tex] \: [/tex]

Given:-

  • [tex] \sf x + 4 - 5 = 6[/tex]

[tex] \: [/tex]

Solution:-

  • [tex] \sf \: x + 4 - 5 = 6[/tex]

[tex] \: [/tex]

  • [tex] \sf \: x + 4 = 6 + 5[/tex]

[tex] \: [/tex]

  • [tex] \sf \: x + 4 = 11[/tex]

[tex] \: [/tex]

  • [tex] \sf \: x = 11 - 4[/tex]

[tex] \: [/tex]

  • [tex] \boxed { \sf \blue{x = 7}}[/tex]

[tex] \: [/tex]

or

  • [tex] \sf \: x + 4 - 5 = 6[/tex]

[tex] \: [/tex]

  • [tex] \sf \: x - 1 = 6[/tex]

[tex] \: [/tex]

  • [tex] \sf \: x = 6 + 1[/tex]

[tex] \: [/tex]

  • [tex] \boxed{ \sf { \color{skyblue}x = 7}}[/tex]

[tex] \: [/tex]
