−132
−84
12
18

Answer 1

Answer:

84

Explanation:

3(4x-8)-6y

solution

=3(4×-2-8)-6×6

=3(-8-8)-36

=3×-16-36

=-48-36

=-84

Answer 2

-84

Explanation:

Substitute the values of x and y in the expression and then simplify. To simply use PEDMAS.

3(4x - 8) - 6y = 3(4*[-2] - 8) - 6*6

First we have to do the multiplication inside the parenthesis. So Multiply 4 and (-2).

= 3 * ( - 8 - 8) - 6*6

= 3* (-16) - 6*6

= -48 - 36

= -84
