Question

Pick the solution from the values given in the bracket for 2x – 12.
(x=-2, 3, 4,-4). Show working for each value.

Answer 1

Answer:

-2= -16

3= -6

4= -4

-4= -20

Step-by-step explanation:

2(-2) -12 = - 4 - 12 = -16

2(3) -12 = 6 - 12 = -6

2(4) -12 = 8 - 12 = -4

2(-4) -12 = -8 - 12 = -20

Answer 2

Answer:

x=2

2x-12=2(2)-12=4-12=-8

x=3

2x-12 =2(3)-12=6-12=-6

x=4

2x-12

=2(4)-12=8-12= -4

x= -4

2x-12

=2(-4)-12

=-8-12

= -20
