Determine wether each ordered pair is a solution of the given equation. 17. y=3x-5; (0,5), (-1,-8) 18. y=-2x+7; (1,,3) 19. -6x+5y=-6; (1,0), (2,6/5) 20. 5x-3y=9; (0,3), (12/5,-1) 21. y=2x^2; (1,2), (3,18) 22. y=2|x|; (-1,2), (0,2) 23. y=^3; (2,8), (3,9) 24. y=x^4; (-1,1), (2,16) 25. y=√x+2; (1,3), (4,4) 26. y=3√x-4; (1,-3), (8,6)

17. No, 18. Yes, 19. Yes, 20. No, 21. Yes, 22. No, 23. No, 24. Yes, 25. Yes, 26. No...to get these, just plug the x-value in for x and y value in for y for each of the points. If one of the points does not work, they are not points on the line.

y = 5 and x = 4

Step-by-step explanation:

You need to get the same number either in front of both x's or both y's.

As there is already a value the same for both y's, we can already subtract the two equations:

5x - -x = 6x

6y - 6y = 0

50 - 26 = 24

6x = 24

Divide both sides by 6 to find x:

6x ÷ 6 = x

24 ÷ 6 = 4

x = 4

Substitute this value into first equation:

5(4) + 6y = 50

20 + 6y = 50

Move the +20 over to the other side making it a -20:

6y = 50 - 20

6y = 30

Divide both sides by 6:

6y ÷ 6 = 7

30 ÷ 6 = 5

So y = 5

This means that y = 5 and x = 4

Hope this helps!
