REASON:
SSS congruency states that, if all the three sides of a triangle are respectively equal to the corresponding sides of another triangle then both triangles are said to be
.
Here, in both triangles
7units=7 units
8units=8units
Middle side is common to both triangles so it is equal.
Hence, both triangles are congruent by SSS

a = 2x + 6xz
a = x(2 + 6z) <em>factored out "x" on right side</em>
a/(2 + 6z) = x <em>divided both sides by (2 + 6z)</em>
Answer: x =
