Simplifying
12x + -8x = 12
Combine like terms: 12x + -8x = 4x
4x = 12
Solving
4x = 12
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Divide each side by '4'.

x = 3
Answer:
160D^2
Step-by-step explanation:
The answer is: " 12 " .
_____________________________________________
→ " x = 12 " .
_____________________________________________
To solve:
________________________________________________________
3x - 1 = x + 23 ; Solve for "x" ;
Subtract "x" from each side of the equation; & add "1" to each side of the equation;
3x - 1 - x + 1 = x + 23 - x + 1 ;
to get:
2x = 24 ;
Divide each side of the equation by "2" ;
to isolate "x" on one side of the equation; & to solve for "x" ;
2x/2 = 24/2 ;
to get:
x = 12 .
_____________________________________________
Let us check our answer, by plugging in "12" for "x" ; on EACH side of the original equation; to see if the equation holds true; {that is, to see if each side of the original equation is equal, when "x = 12" } ; as follows:
______________________________________________
3x - 1 = x + 23 ;
Substitute "12" for "x" on each side ;
3(12) - 1 =? (12) + 23 ??
36 - 1 =? 35 ??
35 =? 35?? Yes!

Answer:
Option A- 1.8x – 10 = –4; x = 1.8 x minus 10 equals negative 4; x equals StartFraction 10 Over 2 EndFraction.
<span>Let's do this step by step, we know that the guy steals $ 100
So it would be - $ 100 for the store.
The men buy $ 70 merchandise WITH THE MONEY THAT HE STOLE, but the money that he stole CAME BACK to the store
So up to this poin, : - $ 100 + $100 - $ 70 = - $ 70 for the store
After that , the store give $ 30 cash back,
So in the and : - $ 70 - $30 = - $ 100 lost for the store
