Answer: FG=7
Explanation:
F is a point on the line segment EG so both line segments (EF & FG) total to 5x+7
This can be modeled by this education:
5x+2x-7=5x+7
First, you should cancel out like terms (subtract 5x from both sides)
Your new equation is:
2x-7=7
Now you want to isolate 2x (so add 7 to both sides to remove the negative). Now you’re left with:
2x=14
To find x, divide both sides by 2. Now we know x=7.
The next step is to add the x value into the equation for the line segment FG
FG=2(7)-7
=14-7
Line segment equals 7
