Answer:
y = x - 7
Step-by-step explanation:
You take each equation and sub in for x and y.
The first equation would look like this:
16 = 2(23) - 30 Then you answer looks like this:
16 = 16 but if you did that for the second set in the column it looks like this:
18 = 2(25) - 30
18 = 50 - 30
18 = 20 which does not equal canceling the first answer.
And the second answer doesn't make sense because if x > y you shouldn't add to x. The same goes for the third answer.
So that leaves only one answer y = x - 7
Hope this helps
Sorry if this answer is long

Let the number of $1 bill be x and $5 bill be y
x=5y
5y+y=48
6y=48
x=40
y=8
number of $1 bill= 40
number of $5 bill = 8
Answer:
a = 10, b = -12
Step-by-step explanation:
4+2(5x-8) = ax +b
4 + 10x - 16 = ax + b
10x - 12 = ax + b
Infinitely many solutions when:
a = 10
b = -12
