Question

What is the solution to the equation the sqaure root of 5x -7 = the sqaure root of 3x + 5

Answer 1

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 2

Answer:

x = 6

Step-by-step explanation:

$\sqrt{5x - 7}$ = $\sqrt{3x +5}$ ( 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
