The given equation is a linear equation so it will have only one equation

Given equation is:

5x+3=2x+15​

<u>Subtraction property of equality:</u>

5x+3-3 = 2x+15-3\\5x = 2x+12

<u>Subtraction property of equality:</u>

5x-2x = 2x-2x+12\\3x = 12

<u>Division Property of Equality:</u>

\frac{3x}{3} = \frac{12}{3}\\x = 4

Hence,

The solution is x = 4
