Question

will fan and give medal


state the property that justifies the statement: If 3x + 4 = 10, then 3x = 6 (1 point)

Answer 1

This question doesn't really demonstrate any particular Algebraic Property that I have written down,
1. Closure: a + b and ab are real numbers
2. Commutative: a + b = b + a, ab = ba
3. Associative: (a+b) + c = a + (b+c), (ab)c = a(bc)
4. Distributive: (a+b)c = ac+bc
5. Identity: a+0 = 0+a = a
6. Inverse: a + (-a) = 0, a(1/a) = 1
7. Cancelation: If a+x=a+y, then x=y
8. Zero-factor: a0 = 0a = 0
9. Negation: -(-a) = a, (-a)b= a(-b) = -(ab), (-a)(-b) = ab

Answer 2

It's really just an example of the golden rule; Any mathematical operation can be performed on one side of an equation so long as the identical operation is performed on the other side of the equation.

Answer 3

you want the answe choices?

Answer 6

Ah, I see.
They're asking, how did we get rid of 4 from each side?

Answer 7

i have no clue.

Answer 8

subtraction... omg im stupid

Answer 9

How do you turn 3x+4 into 3x?

Answer 10

you subtract four from 10 right??

Answer 11

Right!

Answer 12

and then you divide 6 from 3 and get 2 but the answer is the subtracting one right?

Answer 13

In the step that gets you from 3x+4 = 10 to 3x=6
yes, it's subtraction

Answer 14
