4x  - y =  - 5 \\  - 2x + y = 3

Solve the second equation for y

4x - y =  - 5 \\ y = 3 + 2x

Substitute the given value of y into the first equation

4x - (3 + 2x) =  - 5

Solve the equation for x

x =  - 1

Substitute the given value of x into the second equation

y = 3 + 2( - 1)

Solve the equation for y

y = 1

The possible solution of the system is the ordered pair (x,y)

(x,y) = ( - 1, 1)

Answer:

The tree that Laura had to cut had 306 apples.

Step-by-step explanation:

Given that Laura has 78 apple trees in her cider farm, with a mean of 460 apples per tree, but then she has had to get a tree cut down, and after that, the mean of apples per tree became 462, to determine how many apples were there on the tree that Laura had to cut down, the following calculation must be performed:

(78 x 460) - (77 x 462) = X

35.880 - 35.574 = X

306 = X

Thus, the tree that Laura had to cut had 306 apples.
