Easy buddy...

[tex]5x - 15 = 3x + 7[/tex]

Subtract the sides of the equation plus 15

[tex]5x = 3x + 7 + 15[/tex]

[tex]5x = 3x + 22[/tex]

Subtract the sides of the equation minus 3x

[tex]5x - 3x = 22[/tex]

[tex]2x = 22[/tex]

Divided the sides of the equation by 2

[tex]x = \frac{22}{2} \\ [/tex]

[tex]x = 11[/tex]
