Determine whether the given ordered pair is a solution to the system.

(5, 8)

3x - 2y = -1

9y = 4x + 53

Hello,

let's have

x=5 and y=8

3x-2y=3*5-2*8=15-16=-1

9y=9*8=54

4x+53=4*5+53=73

Thus, this is not a solution for your problem.

Substitute 5 for x and 8 for y into each equation and see if it "checks" for both:

3(5) - 2(8) = -1

15 - 16 = -1

-1 = -1

True -> It checks!!

9(8) = 4(5) + 53

72 = 20 + 53

72 = 73

False -> It DOES NOT check.

Therefore, (5, 8) is not a solution of the system.

• all you do is plug in for X and Y

3(5) - 2(8) = -1

15-16 = -1

this one is true, now let's see if it works for the 2nd set

9(8)=4(5) + 53

72= 20 + 53

72= 63

since 72 does not equal 73, this is false

so the given ordered pair is not a solution to the system

• You did no longer grant a device of equations. regardless of they're, however, all you may do is plug a million/4 in for x and -3/4 in for y and notice if the two sides of the equation come out equivalent to a minimum of one yet another. in the event that they do, the respond is actual. If no longer, fake.
