Separate the x- and y-values with a comma.<br> X=-3+y<br> 26x - 5y = 6
labwork [276]

Answer:

The solution of the given system is (x,y) = (1,4)

Step-by-step explanation:

Here, the given system of equation is:

x  = -3 + y

26 x - 5 y =  6

Now, substitute x  = -3 + y in the second equation , we get

26 x - 5 y =  6  ⇒   26 (-3 + y) - 5 y =  6

or, 26(-3)  + 26(y)  - 5y = 6

⇒ - 78 + 26 y - 5y = 6

⇒   21 y =  84

⇒  y = 84 / 21 = 4   or ,   y =  4

So x  = -3 + y  =  -3 + 4 = 1

Hence, the solution of the given system is (x,y) = (1,4)

Solve for the value of k.
OLEGan [10]

Answer:

The value of K is 5

Step-by-step explanation:

I reversed it.

The tiny squares means 90⁰, so 90+49=139

All of these angles add up to 180⁰

So 180-139=41

The k equation equals 41⁰, so reverse it to find answer

41-1=40

40÷8=5
