Question

simplify the following problem using the distributive property 3x +4y + 3(x-y) - 4x Show each step in your calculation. Justify each of your step each of your steps using number properties

Answer 1

3x+4y+3x-3y-4x
6x+4y-3y-4x
6x+y-4x
2x+y

Answer 2

Simplify: 3x + 4x + 3(x-y) - 4x

1. First is set the expression into a standard form such that, 3x + 4y + 3x -3y -4x
2. MDAS, 6x - 4x + 4y -3y
3. Becomes, 2x + y
4. The expression is 2x + y



For the basic properties examples are:
Addition, you can have 6 + 107 = 113
Commutative Property by moving: 107 + 6 = 113
Associative Property by grouping: (3 + 3) + (100 + 7 ) = 113
Distributive Property by allotting: 2 (3) + 107 = 113

Multiplication, you can have 6 x 107 = 642
Commutative Property by moving: 107 x 6 = 642
Associative Property by grouping: (3 + 3) x (100 + 7 ) = 642
Distributive Property by allotting: 2(3) x 107 = 642
