A: y=1500x + 2000
For B, just times 1500 by 1 through 6 plus the 2000
X = (7 + Y) (7 - Y)
2 + Y
21 hundreds would be 2100
Answer:
Quite simply. The answer is X=6
Since you have a full fraction, you can find a common denominator in both fractions and multiply. (The common denominator would be 8, so you would multiply 4 by 2 to get 8. Do the same thing to the top, do multiply 3 by 2 to get 6). Now the fraction is 6/8, and since it's equal to incomplete fraction, you know X is 6.
Try plugging in 4,6, and -7 into the x's
