In an ordered pair, x is the first number and y is the second number. So this is telling you x=1 and y=-5. You can take this information and plug it into the formulas.
x + 2y = -9
1 + 2(-5) = -9
1 + -10 = -9? True
x - y = 6
1 - -5 = 6? *
1 + 5 = 6? True.
(*Subtracting a negative makes it a positive.)

Answer : x=-2,y=4.
The second equation is multiplied by 5 and give it equation (3) and then subtract the first and third equations .You’ll first get the value ‘y’ and then substitute the value of ‘y’ in the first equation.Finally you’ll get the value of ‘x’.
x represents the new value.
This multiplies 660, the starting value, by 110% for each year (t).
Answer:
Step-by-step explanation:
Let n represent the number of friends who went to the movies with you.
Then ($12/ticket)n + $15 = $75. Solving for n, we get:

---------------- = ----------------- = 5 so a total of 5 friends went with you.
($12/ticket) ($12/ticket)
