What is the solution to this system of linear equations?
2x + 3y = 3
7x – 3y = 24
(2,7)
(3,-21)
(3,-1)
(9,0)

(3,-1)

Step-by-step explanation:

Add the two equations together to cancel out the 3y's:  2x +7x + 3y - 3y = 3 + 24

Simplify this down:  9x = 27

Now divide through by 9:  x = 3

Replace x with 3 in either of the equations, I'm going to use the first one since it looks easier:  2(3) + 3y = 3

Simplifiy:  6 + 3y = 3

And rearrange:  3y = -3

Divide by 3:  y = -1

So the answer is (3,-1)

the ratio of white tiles to blue tiles is 48: 16. the ratio in it's simplest form is 3: 1.

step-by-step explanation:

ratio: take the first number and add a colon next to it, then add the second number after that. make sure the ratio order matches up with the written problem!

simplest form: we can simplify the ratio 48 : 16 by dividing both terms by the greatest common factor (gcf).

the gcf of 48 and 16 is 16.

divide both terms by 16:

48 ÷ 16 = 3

16 ÷ 16 = 1

reducing to simplest form:

48 : 16 = 3 : 1

answer: -0.5 would be the most likley outcome
