Hey there!
In order for you to solve this type of pre-algebraic expression you have to break down what the equation is telling (this method can make it easier to solve the problem
So, here's what I meant
[tex] 7 = 7 \\ times = multiplication (*) \\ difference = subtraction (-) \\ y =y \\ one = 1 [/tex]
Now that we got that method out of the way we can solve for our answer in this particular problem:
[tex] 7(y-1) = 7y - 1 \\ \\ \\ Therefore, 7(y - 1) [/tex] [tex] would [/tex] [tex] most [/tex] [tex] likely [/tex] [tex] be [/tex] [tex] your [/tex] [tex] answer! [/tex]
Good luck on your assignment and enjoy your day!
Note: Just [tex] highlight [/tex] your key terms of the equations, it can come in handy
