How do I solve 2x-3y=-1 and y=x-1 with substitution?
Answers
y=x-1 (label 2)
sub 2 in 1
2x-3(x-1)= -1
2x-3x+3= -1
-x+3= -1
-x=-4
x=4
sub x=4 into 2
y=4-1
y=3
therefore x=4 and y=3

Divide the money spent by the price per stock:
2,000 / 15.22 = 131.4
Round to a whole number = 131 stocks.
Answer: The answer is A
Step-by-step explanation:
Okay, so they bought $2000 in shares. The price of stock is $15.22. So, you would divide $2000 into $15.22.
2000 divided by 15.22 is 131.40
Now, I am going to round it. Since it is not over 5 I am gonna round down.
Therefore your answer is 131.
Hope this helps!
