Solve the system of equations and choose the correct ordered pair.
2х - бу = 8
5x - 4 y= 31
оа. (7, -1)
ов. (7,1)
ос. (1,-1)
od. (8, 2)

B)   x  = 7, y = 1 is the Solution of the given system.

Step-by-step explanation:

Here, the given system of equation is:

2х - бу = 8          (1)

5x - 4 y= 31    (2)

Now, to solve the given system, we need to eliminate a variable.

To remove variable x from the system, multiply (1) with 5, and (2) with -2 , we get:

10 x -30 y = 40

-10 x + 8y = -62

Add both equations, we get

10 x -30 y  -10 x + 8y   = 40 - 62

or, -22 y =  -22

or, y = 22/22  = 1  ⇒ y = 1

Putting y = 1 in (1) , we get

2x = 8 + 6 y = 8 + 6(1)  = 14

or, x  = 14/2 = 7

⇒ x = 7

Hence, x  = 7, y = 1 is the Solution of the given system.

answer: i'm not going to give you the answer, but some hints to work it out.

step-by-step explanation: so, if there is a straight line that means that the line angle is 180°. so we subtract the 2 angle measures provided, (15 and 38) from 180. so the answer is 180 - (38 + 15). (you have to solve the equation)

the answer

b. they are parallel and will never intersect.
