Answer:

[tex]x = \frac{2}{3} [/tex]

Step-by-step explanation:

[tex]9 - 7x = (4x - 3)2 + 5[/tex]

[tex]9 - 7x = (4x \times 2 - 3 \times 2 )+ 5[/tex]

[tex]9 - 7x = 8x - 6 + 5[/tex]

[tex]9 + 6 - 5 = 8x + 7x[/tex]

[tex]10 = 15x[/tex]

[tex] \frac{10}{15} = \frac{15x}{15} [/tex]

[tex]x = \frac{10 \div 5}{15 \div 3} [/tex]

[tex]x = \frac{2}{3} [/tex]
