Answer :
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]
