**x=1**

**explaination:**

**2x+3=5x
**

**Subtract 5x from both sides.
**

**2x+3−5x=0
**

**Combine 2x and −5x to get −3x.
**

**−3x+3=0
**

**Subtract 3 from both sides. Anything subtracted from zero gives its negation.
**

**−3x=−3
**

**Divide both sides by −3.
**

**x= **

**−3
**

**−3
**

**
**

** **

**Divide −3 by −3 to get 1.
**

**x=1**
