Answer:

  • x = 6

Step-by-step explanation:

If you square both sides you get:

  • 5x - 7 = 3x + 5

Solve it for x:

  • 5x - 3x = 5 + 7
  • 2x = 12
  • x = 6

Answer:

x = 6

Step-by-step explanation:

[tex]\sqrt{5x - 7}[/tex] = [tex]\sqrt{3x +5}[/tex] ( square both sides to clear the radicals )

5x - 7 = 3x + 5 ( subtract 3x from both sides )

2x - 7 = 5 ( add 7 to both sides )

2x = 12 ( divide both sides by 2 )

x = 6
