Answer:
[tex]y=-11[/tex]
Step-by-step explanation:
So we have the equation:
[tex]y-3(2y-7)=76[/tex]
First, distribute the -3:
[tex]y-6y+21=76[/tex]
Combine like terms on the left:
[tex]-5y+21=76[/tex]
Subtract 21 from both sides:
[tex]-5y=55[/tex]
Divide both sides by -5:
[tex]y=-11[/tex]
So, the value of y is -11.
And we're done!
