Ais right if u want more just write the common factors (the numbers that you multiply)

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

Ican't solve. your equation is impossible. you can't have two equal signs.
