Solve for x: -9x + 1 = -80

Step-by-step explanation:

-9x + 1 = - 80

Take 1 to another side and when it goes to another side it changes its sign and become -

- 9x = - 80 -1

- 9x = - 81

As we can see both sides have minus so it will be cancelled

9x = 81

x = 81/9

therefore x = 9

start with a line segment pq that we will copy. mark a point r that will be one endpoint of the new line segment. set the compasses' point on the point p of the line segment to be copied. adjust the compasses' width to the point q. the compasses' width is now equal to the length of the line segment pq.
