If: 3z = 0.45
Then: z = 0.15 by dividing both sides by 3
None. Properties of inequalities are not that relevant when solving equalities.
You would take 2 and replace it for x in your other equation and solve.
no the equation is not correct, the only way it would be correct is if x=7 which would be a commutative property
This equation is unsolvable since there are two unknowns and only one equation. You would require a second equation in order to solve it.
You'd need another equation to sub in
32
The multiplicative property of equality. Multiply each side by -1/3.
None. Properties of inequalities are not that relevant when solving equalities.
A proper question would help.

You would do it it by oppisites. 3+2+4=9 which equals C.
