Answer:

x = -3 , y = -4

Step-by-step explanation:

$\begin{bmatrix}y=2x+2\\ y=-4\end{bmatrix}$

$\begin{bmatrix}2x+2=-4\end{bmatrix}$

$y=2\left(-3\right)+2$

$y=-4$

$y=-4,\:x=-3$

Another easy way to determine it is to look where the two lines intercept.

dsp73

Answer:

21 pieces of chickens.

Step-by-step explanation:

Given:

The farmer has a total of 40 animals. ( cows and chicken )

He counts the legs of all his animals and realizes he has a total of 118 legs.

Question asked:

How many chickens does the farmer have ?

Solution:

Let number of chickens = $x$

Then number of cows = $40-x$

Now, as here given that total number of legs are 118 of all the animals, and as we know that a chicken has two legs and cow has four legs, hence the equation will be :

Total number of legs = Number of legs having chickens + Number of legs having cows

$118 = 2x+4(40-x)\\118=2x+160-4x$

$118=-2x+160$

Subtracting both sides by 160

$-42=-2x$

By adding both sides by minus

$42 = 2x\\$

By dividing both sides by 2

$x =21$

Hence, farmer have 21 pieces of chickens.
