By collecting like terms we have:
Answer:
commutative property is C+2+0=C+2
(As a+b=b+a is the law of commutative property of addition )
Simplife3^2 to 9
9x-7+2=0
9x-7+2to 9x-5
9x-5=0
add 5 to both sides 9x=5
Divide both sides by 9
x=5/9
It typically just needs two parts
1) all parties must be in agreement
