Question

Solve the given equation.

3+ √ 9x + 4 = 18

Answer 1

X= 11/9

Step-by-step explanation:

Answer 2

221/9

Step-by-step explanation:

3+ sqrt( 9x + 4) = 18

Subtract 2 from each side

3-3+ sqrt( 9x + 4) = 18-3

sqrt( 9x + 4) = 15

Square each side

(sqrt(9x+4))^2 = 15^2

9x+4 = 225

Subtract 4 from each side

9x = 225-4

9x = 221

Divide by 9

x = 221/9
