1. 3radical2x = 12
divide by both sides
3radical 2x/3 = 12/3
radical 2x = 4
Then shift the radical to other side
It will be, 2x = 4^2
Then, 2x = 16
Divide by two both sides
2x/2 = 16/2
X = 8
2. Radical3x + 5 = 11
Collect like times by shifting 5 to the other side
It will be, Radical3x = 11 - 5
Radical3x = 6
Then shift the radical to other side at it will become square
So, 3x = 6^2
3x = 36
Divide 3 both 3x/3 = 36/3
X = 12
3. Radical(5x + 2) - 3 = 0
Radical(5x + 2) = 3
5x + 2 = 3^2
5x = 9 -2
5x = 7
5x/5 = 7/5
X = 7/5
