An angle measures 79 degrees, and a circle is centered at the angle's vertex. The subtended arc along this circle is how many times as long as 1/360th of the circle's circumference

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
