The answer is the first two inequalities ........
Here x=3
so, putting 3 instead of x
∠DCE = ∠BAE because of alternate interior ∠s
∠CDE = ∠ABE because of alternate interior ∠s
Triangle DCE is congruent to Triangle BAE because of ASA
AE = CE because of CPCTC
BE = DE because of CPCTC
Answer:
2x−3=x
Move all terms containing x
to the left side of the equation.
Subtract x
from both sides of the equation.
2x−3−x=0
Subtract x
from 2x
x−3=0
Add 3
to both sides of the equation.
x=3
