Answer:

W= 1, J=9 and A= 8

Step-by-step explanation:

Given equation: WW+JJ+AA=WJA and the values must be positive integers and different from each other.

Now find the value for W, J, and A.

The two digit number has 10th digit and unit digit

∴ WW= 10W+W= 11W

   JJ=  10J+J= 11J

   AA= 10A+A= 11A

In equation we can write as 11W+11J+11A= WJA

Similary for three digit number, it has 100th digit, 10th digit and unit digit.

∴ WJA= 100W+10J+A

In the given equation we can write as 11W+11J+11A= 100W+10J+A

Solving the equation now,

11W+11J+11A= 100W+10J+A

Subtracting 11W, 10J and A on both side

⇒ J+10A= 89W

Remember, the values must be positive integers and different from each other.

Now using the value between 1 to 9 to make equation equal.

If we use 1 for W, 8 for A and 9 for J

⇒ 9+10\times 8= 89\times 1

⇒ 89=89

∴ Value will be W= 1, J= 9 and A= 8.

Which system of equations is incondsistent? a. 2x+8y=6 5x+20y=2
galina1969 [7]

Answer: Yes

Step-by-step explanation:

2x+8y=6

-8y -8y

2x = -2y

Divide by two so x will be by itself, so the answer will be -1y.

5x+20y=2

-20y -20y

5x = -18y

Divide by 5 so x will be by itself, so the answer will be -3y.

Solve the system of linear equations. <br> −8x+5y=26<br> 9x−3y=−3
Sloan [31]

Answer: x = 3 and y = 10

Step-by-step explanation:

-8x + 5y = 26     .................. equation 1

9x - 3y = -3          ................ equation 2

Solving the system of linear equations by elimination method.

The means we have to make the coefficient of one of the variable the same in order to eliminate the variable first.

Let us eliminate the variable y first , this means we will multiply equation 1 by 3 and multiply equation 2 by 5. Doing this , we have

-24x + 15y = 78      ............. equation 3

45x - 15y = -15     ................ equation 4

Now that we have the same coefficient , we have to check their signs , if the have the same signs , we will subtract , that is , if both are having positive signs , we will subtract , if both have negative signs , we will also subtract but if their signs differ we will add. Following this rule and considering the equations above , the coefficients of y have different signs , so we will add equation 3 and equation 4 , so we have:

21x = 63

x = 63/21

x = 3

Substitute x = 3 into equation 1 or equation 2 to get the value of y , using equation 2 , we have

9x - 3y = -3

9(3) - 3y = -3

27 - 3y = -3

27+3 = 3y

30 = 3y

30/3 = y

Therefore y = 10

Therefore : x = 3 and y = 10
