What are the steps to solving <br> 3x=4+2(3−x).

masya89 [10]

Answer:

x = 2

Step-by-step explanation:

How to find "x"

3x = 4 + 2(3 - x) *Remove the parentheses*

3x = 4 + 6 - 2x *Calculate*

3x = 10 - 2x *Move the variable to the left*

3x + 2x = 10 *Collect the terms*

5x = 10 *Divide both sides*

x = 2

I hope the helped!!!
