Solve the system using elimination.
2x + 3y = -2
3х – 6у = 18

x = 2 and y = -2

Step-by-step explanation:

We must first eliminate the y-variable:

2x + 3y = -2

3x - 6y = 18

4x + 6y = -4

3x - 6y = 18

7x = 14

x = 2

Since we know x=2, we plug that back into one of the original equations to find y:

2x + 3y = -2

2(2) + 3y = -2

4 + 3y = -2

3y = -6

y = -2

Therefore, x = 2 and y = -2

Step-by-step explanation:

2x+3y= -2 1

3x - 6y = 18 2

Multiply both Sides of equation 1 by 2

4x + 6y = -4

3x - 6y = 18

(add Like terms)

7x = 14 (devide both Sides by 7)

.°. x = 2

Substitude x = 2 into equation 1

.°. 2(2) + 3y = -2 (multiple the digit)

4 + 3y = -2 (Move 4 to the right and change it's sign)

3y = -6 (devide both side by 3)

y = -2

Final answers x = 2 ; y = -2

{2 ; -2}

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.

c) the median for town a 30" is greater than the median for town b 25"

step-by-step explanation:

town a, median = q2 = 30

town b, median - q2 = 25

so the median for town a 30" is greater than the median for town b 25"
