Use the relation 2x+y=10 to find the missing values.

x= 5 -y/2

y=10-2x

Step-by-step explanation:

solve for Y                solve for X        

2x + y= 10                   2x+ y=10              subtract y from each side

-2x        -2x                       -y=10 -y

       y=10-2x                    2x=10 -y

                                        2x/2=  10 -y/2  multiply both sides by 2

                                              x= 5 - y/2

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.
