Solve, using linear combination. 11x + 4y = 18 3x + 4y = 2 (4, –5) (2, –1) (2, 1) (2, 0)

(2,-1)

Step-by-step explanation:

You just plug in the numbers. The order always starts as x then y. Basically that means in (2,1), the 2 would be the x and the 1 would be the y. In (4,-5), the 4 would be the x and the -5 would be the y and so forth.

Once you plug it in you get:

11(2)+4(-1)=18

3(2)+4(-1)=2.

When you plug the 2 and -1 in, they do equal 18 and 2 so you know that's the answer! :)

20

step-by-step explanation:

i think there was a typo. you wrote pat brings 3 quarts of ice-cream to the party. each serving of ice-cream is 1 6 quart. how many total servings of ice-cream does pat bring to the party? i think the bold is supposed to be 1/6. so 1 quart of ice cream = 6 servings. 6 * 3 = 18.
