Answer:

x = 3

Step-by-step explanation:

Given the 2 equations

x + y = 3 → (1)

2x - y = 6 → (2)

Adding the 2 equations term by term eliminates the y- term, that is

3x = 9 ( divide both sides by 3 )

x = 3

kotykmax [81]

Answer:

Altogether they sell 1634 apples.

Step-by-step explanation:

GIven:

Bob, Joe and Larry sold apples at the farmers market.

Bob sold 86 apples.

Joe sold 12 times as many as Bob.

Larry sold half as many apples as Joe.

Now, to find the total apples Bob, Joe and Larry they all sell together.

Number of apples Bob sold = 86.

Number of apples Joe sold = 12 times of 86.

$=12\times 86\\\\=1032.$

Number of apples Larry sold = $\frac{1}{2}\ of\ 1032$

$=\frac{1}{2} \times 1032$

$=516.$

Now, to get the apples they sell altogether we add the number of apples sold by Bob, by Joe and by Larry:

$86+1032+516$

$=1634.$

Therefore, altogether they sell 1634 apples.
