Answer:

[tex]y=3[/tex]

Step-by-step explanation:

[tex]-2(7 - y) + 4 = -4[/tex]

➱ Subtract 4 from both sides:

  • [tex]-2\left(7-y\right)+4-4=-4-4[/tex]
  • [tex]-2\left(7-y\right)=-8[/tex]

➱ Divide both sides by -2:

  • [tex]\frac{-2\left(7-y\right)}{-2}=\frac{-8}{-2}[/tex]
  • [tex]7-y=4[/tex]

➱ Subtract 7 from both sides:

  • [tex]7-y-7=4-7[/tex]
  • [tex]-y=-3[/tex]

➱ Divide both sides by -1:

  • [tex]\frac{-y}{-1}=\frac{-3}{-1}[/tex]
  • [tex]y=3[/tex]
