Answer:

x = [tex]\frac{8y-7}{3y-6}[/tex]

Step-by-step explanation:

Given

y = [tex]\frac{6x-7}{3x-8}[/tex] ( multiply both sides by 3x - 8 )

y(3x - 8) = 6x - 7 ← distribute left side

3xy - 8y = 6x - 7 ( subtract 6x from both sides )

3xy - 6x - 8y = - 7 ( add 8y to both sides )

3xy - 6x = 8y - 7 ← factor out x from each term on the left

x(3y - 6) = 8y - 7 ← divide both sides by (3y - 6)

x = [tex]\frac{8y-7}{3y-6}[/tex]
