Answer:
Isolate the variables in all cases. Note the equal sign, what you do to one side, you do to the other.
a) 3x = 18
Isolate the variable, x. Divide 3 from both sides:
(3x)/3 = (18)/3
x = 18/3
x = 6
b) 2x = 9
Isolate the variable, x. Divide 2 from both sides:
(2x)/2 = (9)/2
x = 9/2
x = 4.5
c) (x/5) = 7
Isolate the variable, x. Multiply 5 to both sides:
(x/5)(5) = (7)(5)
x = 7 * 5
x = 35
d) x/2 = 6.5
Isolate the variable, x. Multiply 2 to both sides:
(x/2)(2) = (6.5)(2)
x = 6.5 * 2
x = 13

Answer:
It is congruent
Step-by-step explanation:
Because AB and BC are congruent, having DE bisect them
directly in the middle creates equal lines of BD and BE.
