-4x -2y = 12
-x + 4y = 12
Multiply the first equation 2 then add to the second equation.
-8x -4y = 24
-x + 4y = 12
___________
-9x = 36
Divide both sides by-9
x = -4
Plug -4 back into either original equations and solve for y.
- -4 + 4y = 12
4 + 4y = 12
Subtract 4 from both sides
4y = 8
Divide both sides by 4
y = 2
(-4,2)

A bowl of fruit is on the table. It contains 5 apples, 2 oranges, and 2 bananas. Christian and Aaron come home from school and r
Sholpan [36]

The probability that both grab oranges would be = \frac{1}{36}

Step-by-step explanation:

Given,

A bowl contains,

Apples = a = 5

Oranges = o = 2

bananas = b = 2

Total fruits in bowl = x = a + o + b = 5 + 2 + 2 = 9

Now, Christian and Aaron come home from school and randomly grab one fruit each.

The probability of first selecting orange would be = \frac{o}{b} = \frac{2}{9}

Now, the oranges left would be 2 - 1 = 1

and total fruits would be = 9 - 1 = 8

Hence, the probability of selecting second orange would be = \frac{1}{8}

Therefore, the probability that both grab oranges would be = \frac{1}{8} * \frac{2}{9} = \frac{1}{36}
