Answer:

x = - [tex]\frac{57}{22}[/tex]

Step-by-step explanation:

Given

[tex]\frac{4}{6x+3}[/tex] = [tex]\frac{7}{5x-9}[/tex] ( cross- multiply )

7(6x + 3) = 4(5x - 9) ← distribute parenthesis on both sides

42x + 21 = 20x - 36 ( subtract 20x from both sides )

22x + 21 = - 36 ( subtract 21 from both sides )

22x = - 57 ( divide both sides by 22 )

x = - [tex]\frac{57}{22}[/tex]
