Pls help I really need a good grade on this

Answer:
[tex]y=78[/tex]
Step-by-step explanation:
[tex]\frac{y}{13}-2=4[/tex]
[tex]\frac{y}{13}-2+2=4+2[/tex] (Add [tex]2[/tex] to both sides to isolate [tex]y[/tex])
[tex]\frac{y}{13}=6[/tex] (Simplify)
[tex]\frac{y}{13}*13=6*13[/tex] (Multiply both sides of the equation by [tex]13[/tex] to get rid of the denominator)
[tex]y=78[/tex] (Simplify)
Hope this helps!
