which property did the student use for the first strip ? explain why this property is correct !

the arrangement

Step-by-step explanation:

i=3a+6=2-5a+7. (2) start taking like terms 3a+6=2+7-5a(iii)

3a-5a=2+7-6 (3)calculate(iv)8a=3. (4)solve for a (v)8a/8=3/8=0.38. The property is correct because she is collecting like terms to be able to solve for a.
