Hello from MrBillDoesMath!
Answer:
Choice D, x = 9
Discussion:
Triangles EFG and EDG are congruent by SAS.
* Side = they both have a side of length 13.
* Angle = base angles F and D are equal as the triangles are isosceles.
Because of that, angles FEG and DEG are equal
*Side = they both share EG
Hence corresponding parts are equal, so FG = DG or
5x - 17 = 3x + 1 => (adding 17 to both sides)
5x - 17 + 17 = 3x + 1 + 17 =>
5x = 3x + 18 => (subtract 3x from both sides)
5x -3x = 18 =>
2x = 18 =>
x = 9
which is choice D

The short answer is to solve one equation for one variable, then swap that variable in a different equation.
Example:
2x + 2y = 6
y-x = 1
Step 1: solve either equation for a variable: (#2) y = x+1
Step 2: substitute for your solved variable (I can substitute x+1 for y)
(#1) 2x + 2(x+1) = 6
2x + 2x + 2 = 6
4x + 2 = 6
4x = 4
x = 1
now use x=1 to solve for y in either original equation
