P has a y intercept of 6 and a slope of 1 up for every two to the right, 1/2

y = (1/2) x + 6

Q has a y intercept of -3 and a slope of 4 down from every one to the right, -4.

y = -4x - 3

For the solution we equate the two ys,

(1/2)x + 6 = -4x - 3

x + 12 = -8x - 6

9x = -18

x = -2

y = (1/2) (-2) + 6 = 5

Solution: (x,y)=(-2, 5)

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)
