Put the line on the graph and show me solution

Step-by-step explanation:

Draw a horiz. line.  Locate x = -7 on this line.  It will be 7 units to the left of the origin.  Now draw a vertical, dashed line thru x = -7.  Shade the area to the right of this dashed line.  The shaded area represents the solution set of x > -7.

hello :

70y^8 + 30y^6 = 2 ( 35 y^8 + 15y^6)

the lenght is : 35 y^8

the width is : 15y^6
