∆ABC and ∆FDE are congruent by the SSS

criterion.

x + 3 = 14    |subtract 3 from both sides

x = 11

subtitute the value of x to the equation x - y = 3

11 - y = 3    |subtract 11 from both sides

-y = -8    |change the signs

y = 8

Answer: x = 11 and y = 8.

In the case above, The value of x is 11, and the value of y  is 8.

What is the angle about?

Note that ∆ABC and ∆FDE are said to be congruent using the SSS theorem.

SO x + 3 = 14    

(subtract 3 from both sides)

Then x = 11

So one need to  substitute the value of x to the equation x - y = 3

Then 11 - y = 3    

(Note one have to subtract 11 from both sides)

So -y = -8  

y = 8

Therefore, In the case above, The value of x is 11, and the value of y  is 8.
