2x + y = 3
3x - y = 12
Add both equations
5x = 15, x = 3
2(3) + y = 3
6 + y = 3, y = -3
Solution: x = 3, y = -3... or (3,-3)
Answer:
27p4-27p2-12p+12/p
Step-by-step explanation:
Answer:
$2.04
Step-by-step explanation:
Note that: 1 yard = 3 feet.
First, change the amount of yard (6) to feet:
6 x 3 = 18
6 yard = 18 feet.
Note: 18 feet = $36.72
Find the cost per foot (1 feet). Note the equal sign, what you do to one side, you do to the other. Divide 18 from both sides.
(18 ft)/18 = ($36.72)/18
1 ft = 36.72/18
1 ft = 2.04/1
1 ft = $2.04
