3x + 3 = -2x + 2 - 4
3x + 3 = -2x - 2
Add 2 to each side
3x + 5 = -2x
Subtract -3x from both sides
5 = -5x
Divide each side by 5
1 = -x
Since you can leave x negative you reverse it with 1 and your answer will be >>> x = -1

-1 is the answer.
(Distribute 3 through the parenthesis and then distribute-2 through the parenthesis)
3x+3 = +2x+2-4
(Move the variable to the left side and change its sign and then move the constant to the right side and change its sign)
3x+2x = -2-3
(Collect the like and then calculate the sum or difference)
5x = -1
(Divide both sides of the equation by 5)
x = -1

AURORKA [14]

To solve this problem we can use simple proportion
If
270$ -------------------------3000 pesos
x $ ---------------------------100 pesos (x$ means that we dont know how much)
Now we crossmultiplying to get proportion
x*3000=270*100
Now we just to solve eq
3000x=27000 /:3000
x=27000:3000
x=9$ - its the result
