Find the value of the expression (3x - 12) - (xy - 10) for x = 3 and y = 6.

-11

Step-by-step explanation:

(3x - 12) - (xy - 10) = ?

Substitute your values in for x and y.

[3 (3) - 12] - [ (3) (6) - 10] = ?

Solve. (Remember, two variables next to each other implies multiplication!)

(9 - 12) - (18 - 10) = ?

-3 - 8 = - 11

Step-by-step explanation:

(3x - 12) - (xy - 10) for x = 3 and y = 6

= {3 (3) - 12} - {3 (6) - 10}

= (9 - 12) - (18 - 10)

= - 3 - 8

= - 11
