3x+2y= -19 solve by elimination of addition<br> -3x-5y= 25
tensa zangetsu [6.8K]

Answer:

x=-5, y=-2

Step-by-step explanation:

3x+2y= -19  

-3x-5y= 25

Add the two equations together

3x+2y= -19  

-3x-5y= 25

------------------

0x -3y = 6

Divide each side by -3

-3y/-3 = 6/-3

y = -2

Now find x

3x+2y = -19

3x +2(-2) =-19

3x-4 = -19

Add 4 to each side

3x -4+4 = -19+4

3x= -15

divide by 3

3x/3 = -15/3

x = -5

Which expression has a value that is equivalent to 5n+13 when n= -5
maks197457 [2]

Answer:

Option A is correct.

4n + 8 expression which has a value that is equivalent to 5n+13 when n = -5

Step-by-step explanation:

Given the expression: 5n + 13

If n = -5

then, by substituting in given expression we get;

5(-5)+13 = -25+13 = -12

Option A:

4n + 8

Substitute the value of n = -5 we have;

4(-5) + 8 = -20 + 8 = -12

Option B:

2n + 2

then;

2(-5) + 2 = -10 + 2 = -8

Option C :

n^2+13

then;

(-5)^2+13 = 25 + 13 = 38

Option D:

n + 8

then;

-5 + 8 = 3

Therefore, only option A has expression which has a value that is equivalent to 5n+13 when n = -5
