A system of equations that has no solution is called inconsistent
Leto [7]
In situations such as this one, why not look up the technical vocabulary, so that you can be sure of its meaning?  I did that and found that my recollection of "inconsistent equations" was correct.

TRUE.

How do I find x and y using what is in the equation
Tatiana [17]

y is part of a right angle on line AB

 a right angle = 90 degrees

 90-47 = 43 degrees

y = 43 degrees

a straight line = 180 degrees

180-47 = 133 degrees

 x = 133 degrees

Explain answer ! <br><br> Will give brainlst
Ne4ueva [31]

Answer:

x = 4, y = 2

Step-by-step explanation:

Start by multiplying the first equation by 2:

2x + 2y = 12 --> 4x + 4y = 24

Subtract the second from the first:

   4x + 4y = 24

-   5x + 4y = 28

4x - 5x = -x

4y = 4y = 0

24 - 28 = -4

so you end with -x + 0 = -4

Solve for x to get x = 4

Plug x = 4 back into 2x + 2y = 12 to find y.

2(4) + 2y = 12

8 + 2y = 12

2y = 4

y = 2
