Question

When solving this system of linear equations with the elimination method,
you can multiply the bottom equation by 3.
3x +6y - 38
3( 5x - 2y) = 3(-30)
This step works because of the
O A. commutative property
O B. multiplication property of equality
O C. distributive property
O D. addition property of equality

Answer 1

Answer:

B.

Step-by-step explanation:

Multiplication property of equality.

A simple example is

 x = x    Multiply by 3:

3x = 3x

Answer 2

This step works because of the distributive property - option C.

System of Linear Equations

System of linear equations is the given term math for two or more equations with the same variables. The solution of these equations represents the point at which the lines intersect.

Properties of Multiplication

The properties of multiplication are:

• Distributive:  a(b±c)=  ab±ac
• Comutative:   a . b = b. a
• Associative:    a(b+c)=  c(a+b)
• Identity: b.1=b

For the given system linear system was used the distributive property. Because it was used as a common factor to multiply an expression with a sum.
