Answer:
none of these have the solution of x = -4
Explanation:
1 . 3x + 6 - 2x = -2 . (combine like terms)
x + 6 = -2 (isolate the variable)
-6 -6
x = -8 *x doesn't equal - 4*
2. 2(2 - 4) = 16 (distributive property)
2 - 8 = 16
-6 = 16
since theres no x in the equation its not a possible answer .
3 . (x + 6) 3 = - 6
this one also isn't a proper equation to find x
4. -x + 4 = 3 (isolate the variable)
-4 -4
-x = -1
/x . /x
x= -1
