5 √(3x - 2) - 3 = 7
5 √(3x - 2) = 10
√(3x - 2) = 2
3x - 2 = 4
3x = 6
x = 2
Check:
5 √(3(2) - 2) - 3 = 7
5 √4 - 3 = 7
5(2) - 3 = 7
10 - 3 = 7

first move the 3 to the other side then divide by 5
now you get the â(3x - 2 = 2
take the square and you get 3x-2=4
3x=6
x=2

adding 3
5rt(3x-2)=10
dividing by 5
rt(3x-2)=2
squaring
3x-2=4
adding 2
3x=6
dividing by 3
x=2

Plug that equation into the Google search bar. Great calculator tool

ya. Add three on both sides to get 5*SQRT(3x-2) = 10
Divide by 5 to get SQRT(3x-2)=2
Square both sides to get 3x-2 = 4
You should be good from there.
