Answer: 5
Step by step:
(3x+4)/2 = 9.5
3x+4 = 9.5*2
3x+4 = 19
3x = 19 -4
3x = 15
x = 5
the answer is D. All points to the left of zero are negative.
- 5 = -7 .
____________________________________________This would be one way to write the expresion/equation; in which "x" represents the unknown number.
Now, to solve for "x" ;
____________________________________________Given:
____________________________________________ - 5 = -7 ;
Add "5" to EACH SIDE of the equation:
_____________________________________________ - 5 + 5 = -7 + 5 ;
to get:
= -2 ;
x = (-2 * 3) ;
_________________________________x = - 6 .
