3(y + 4) - (x - 1)
x = 3
y = 2
First plug in the numbers into the variables. Or plug in 3 for "x" and 2 for "y" in the equation.
3(y + 4) - (x - 1)
3(2 + 4) - (3 - 1) Simplify the numbers in the parentheses
3(6) - (2)
18 - 2 = 16
Not sure why, but I wasn't able to post my solution as text, so I've written it elsewhere and am posting screenshots of it here.
In the fifth attachment, the first solution is shown above the second one.
$6x$5=$30
$50-$30=$20
So 5 books?
Or
50=6x5+x
x=20
Answer:
142.
Step-by-step explanation:

=852/6
=142
32(6+4) =320 you need to find the common term and then place on ouside of the parentheses
