Answer:

B) a + 2(a - 3) = 15

Step-by-step explanation:

To see which equation has a = 7, we have to plug 7 into a each time until we find a satisfied equation.

A:

  • [tex]4(7)-4(14-7)=24[/tex]
  • [tex]28-4(7)=24[/tex]
  • [tex]28-28=24[/tex]
  • [tex]0\neq 24[/tex]

B:

  • [tex]7+2(7-3)=15[/tex]
  • [tex]7+2(4)=15[/tex]  
  • [tex]7+8=15[/tex]
  • [tex]15=15[/tex]

Therefore, B is the correct answer.
