Line up the equations and add them up, adding the x's together then y's (which should cancel out) then the totals.
Then the equation should equal -9x=36 and when tou solve x= -4.
Plug -4 in for x in one of the equations, I chose the second one, and solve.
y = -21
Hope this helps! :)

Answer: 1320 (choice C)</h3>
Explanation:
There are 12 choices for left field.
Then there are 12-1 = 11 choices for right field.
Lastly, there are 11-1 = 10 choices for center field.
In total we have 12*11*10 = 1320 different permutations or orderings.
In standard form it would be 20 + 2/x
Answer:
Amount of orange = 1.25 pound
Step-by-step explanation:
Given:
Total amount of apple = 2.5 pound
Total cost = $4.5
Missing cost;
Orange = $1.2 per pound
Apple = $1.2 per pound
Computation:
Assume amount of orange = x
So,
1.2(x) + 2.5(1.2) = 4.5
1.2 x + 3 = 4.5
1.2 x = 1.5
x = 1.25 pound
Amount of orange = 1.25 pound
