What property is used to change the sum of 18+6 to the equivalent expression 6(3+1)
Fittoniya [83]

The distributive property is used to get the equivalent expression

Step-by-step explanation:

The properties on mathematical expressions are used to simplify or elaborate the expressions.

One of the propoerties is distributive properties

The distributive property states that:

Let a, b and c be three integers then

a(b+c) = ab+ac

The property can be used both ways

In given expression

18+6

= 6.3+ 6.1\\=6(3+1)

The distributive property is used to get the equivalent expression

Solve using elimination<br><br> 2x+5y=34<br> x+2y=14
Darina [25.2K]

2x + 5y = 34

x+2y = 14


Multiply the second equation by two to create like terms for one variable.

2(x+2y = 14)

2x + 4y = 28


2x + 5y = 34

2x + 4y = 28 -- Subtract.


y = 34.28 = 6


Solve for x


x + 2(6) = 14

x + 12 = 14

x = 2


Check:

2 + 2(6) = 14

2 + 12 = 14

14 = 14


Answer:

X = 2

Y = 6
