Alice solved the following equation:

-18 - 3x = 12
-3x = 6
x =-2

Which of the following statements is true?



Alice is correct.

The 6 should be 30 in step two.

The 6 should be -6 in step two.

The 6 should be -4 in step two.

Sagot :

The 6 should be 30 in step 2 because you have to add 18 to both sides to cancel out the -18.
apologiabiology
so
-18-3x=12
to get to -3x=12+-somthing
we must add 18 to both sides or
+18-18-3x=12+18
-3x=30
so 'The 6 should be 30 in step 2' is correct
x=-10
