Iam really stuck on this and need to match which goes with what.

1. commutative property of addition (can change the order of addition operations)

2. distributive property (alternative to order of operations you can multiply coefficient by each term in parenthesis)

3. associative property of multiplication (move in and out of parenthesis)

4. commutative property of multiplication (can change the order of multiplication operations)

5. associative property of addition

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
