X+ 3y = 7 x - 3y = 1 solve the system of equations. a) x = 4, y = 1 b) x = 1, y = 4 c) x = - 2 3 , y = 3 d) x = 3, y = - 2 3

Option A.

Step-by-step explanation:

The given system of equations is

        ... (1)

       ...(2)

We need to solve the system of equations.

On adding equation (1) and (2), we get

Divide both sides by 2.

Substitute x=4 in equation (1).

Divide both sides by 3.

Since x=4 and y=1, therefore the correct option is A.

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.
