[tex]19x + 3 = (9 + 6)x + (15 + 16) \\ [/tex]
[tex]19x + 3 = 15x + 31[/tex]
Subtract sides 3
[tex]19x + 3 - 3 = 15x + 31 - 3[/tex]
[tex]19x = 15x + 28[/tex]
Subtract sides 15x
[tex] - 15x + 19x = - 15x + 15x + 28 \\ [/tex]
[tex]4x = 28[/tex]
Divide sides by 4
[tex] \frac{4x}{4} = \frac{28}{4} \\ [/tex]
[tex]x = 7[/tex]
