We assume that the equation is:


5x-(x+3)=3(2-2x)+x

To solve this equation, we need to solve, first, the corresponding operations:

1. We need to apply the distributive property to both sides of the equation (on the left side the number is -1):


5x-x-3=3\cdot2-3\cdot2x+x

2. Sum (algebraically) the like terms:


4x-3=6-6x+x\Rightarrow4x-3=6-5x

3. We need to add 5x to both sides of the equation (this is the addition property of equality):


4x+5x-3=6-5x+5x\Rightarrow9x-3=6

4. Add 3 to both sides of the equation (we apply the same property):


9x-3+3=6+3\Rightarrow9x=9

5. Finally, divide both sides by 9 (this is the division property of equality):


(9x)/(9)=(9)/(9)\Rightarrow x=1

We can check this result by substituting the value of x = 1 in the original equation:


5x-(x+3)=3(2-2x)+x

For x = 1, we have:


5(1)-(1+3)=3(2-2(1))+1_{}
5-4=3(2-2)+1\Rightarrow1=3(0)+1\Rightarrow1=1

The last result is true. Then, we have checked that the answer is correct.

In summary, the solution for the equation is x = 1.
