Question 146111
Let x = "a number"
then
-x = "opposite of the number'
:
Just write what it says (the word "is" usually means "=":
twice a number is 12 less than 6 times the opposite of the number
2x = 6(-x) - 12
2x = -6x - 12
2x + 6x = -12
8x = 12
x= {{{(-12)/8}}}
x = -1.5; (the opposite would be +1.5)
:
:
Check solution in original statement
2(-1.5) = 6(+1.5) - 12
-3 = +9 - 12
