Use the linear combination method to solve this system of equations. what is the value of x

x = -3 2/3

Step-by-step explanation:

Adding the two equations gives the value of y:

(3x +7y) + (-3x -2y) = (31) + (-1)

5y = 30

y = 6

Substituting this value into the second equation, we have ...

-3x -2(6) = -1

-3x = 11 . . . . . . . . . . add 12

x = -11/3 = -3 2/3 . . divide by the coefficient of x

i need more info. are you looked to see there mph? how much they deliver? how far they go?

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.
