The expression 3 radical 18 is equivalent to a) 9 radical 2 b) 3 radical 2 c) 3 radical 6 d) 9 radical 3

12x+8-x=12x-x+8=11x+8=11

If that's an answer

You move the constant to the right side and change its sign to be 9z= -6 -8. that’s the first step.the second step would be calculate the difference of -8-6 to get -14. you equation should now be 9z=-14the last step is to divide both sides by 9 to get z=-14/9hope this
