AB = BC, so 3x-2 = 2x+4. Also, BC = CA, so 2x+4=x+10.
Solve this system of linear equations:
3x-2 = 2x+4
2x+4=x+10 => x=6
Check: Does AB=BC? Does AB=BC?
Does 3(6)-2 = 2(6)+4? Does 16=16? YES.
Does BC = CA? Does 2(6)+4 = 6+10? YES
x = 6 (answer)
REAL NUMBER, RATIO NUMBER
Select every number from -8 to -4 since
-8/-2=4 so we can’t go any bigger since it’s already at 4
Making k equivalent to -8
3/4 is as simple as it gets
