Question

What is the answer of 12(x - 4) = 144

Answer 1

Answer:

x= -16

Step-by-step explanation:

You would expand brackets

12xX and 12x4

this would result in:

12x-48= 144

you would then cancel 48 by plus

so

+48= +48

this would get

12x=192

you want x by itself so divide 12x by -12  (to cancel them out) and  192 by -12

THIS would equal:

x= -16

Answer 2

Answer:

x= 16

Step-by-step explanation:

12(x-4) = 144

(Divide 12 both sides)

x - 4 = 12

(add 4 both sides)

x = 16
