Solve Ax − By = C for x. x equals the quantity negative B times y plus C all over A
x equals the quantity negative B times y minus C all over A
x equals the quantity B times y minus C all over A
x equals the quantity B times y plus C all over A

For this case we have the following equation:

Ax - By = C

From here, we must clear the value of x.

Adding By on both sides:

Ax = By + C

Then, dividing both sides by A we have:

x =By +C/A

x = By+C/A

x equals the quantity B times and plus C all over 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.
