The equations 2 x minus y = negative 2, 3 x + 2 y = 5, 4 x minus y = 2, and 22 x + 10 y = 7 are shown on the graph below. On a c
KiRa [710]

Answer:

<em>The correct answer is First option</em>:

22x+10y=7\\ 2x-y=-2

Step-by-step explanation:

We are given 4 equations:

22x+10y=7\\ 2x-y=-2\\3x+2y=5\ and\ \\4x-y=2

Let us solve the first two:

22x+10y=7...... (1)\\ 2x-y=-2 ...... (2)

Multiplying (2) with 10 and adding to (1):

22x+20x=7-20\\\Rightarrow 42x=-12\\\Rightarrow x = -0.2857 \approx -0.3

So, approximately, value of x is -0.3.

Putting value of x in (2):

2 \times -0.3 - y =-2\\\Rightarrow y = -0.6+2\\\Rightarrow y = 1.4

value of x is approximately -0.3 so y is approximately 1.4.

So, the solution is \approx (–0.3, 1.4)

<em>The correct answer is First option</em>:

22x+10y=7\\ 2x-y=-2

The above two equations have a solution <em>approximately (–0.3, 1.4).</em>

2/4 --> Once simplified by dividing each fraction part by 2 can get 1/2 

4/8 --> Once simplified by dividing each fraction part by 4 can get to 1/2 

2/5 --> Cannot be simplified by any numbers 

7/14 --> Once simplified by dividing each fraction part by 7 can get to 1/2
