Answer:

[tex]x = \dfrac{7y - 4 }{2y +5 }[/tex]

Step-by-step explanation:

Given that:

[tex]y =\dfrac{4-5x}{2x-7}[/tex]

If we cross multiply the above expression, we have:

y(2x - 7)= 4 - 5x

2xy - 7y = 4 - 5x

2xy +5x -7y + 4 = 0

x(2y +5) -7y + 4 = 0

x(2y + 5) = 7y - 4

Divide both sides by (2y+5)

[tex]\dfrac{x(2y + 5)}{2y + 5} = \dfrac{7y - 4 }{2y +5 }[/tex]

[tex]x = \dfrac{7y - 4 }{2y +5 }[/tex]
