Mathematics
1 answer:
julia-pushkina [17]3 years ago
6 0

Answer:

x = - 7

Step-by-step explanation:

Given that the terms are in AP , then

a₃ - a₂ = a₂ - a₁ , substitute values

3x + 4 - (2x - 1) = 2x - 1 - (2x + 1) ← distribute and simplify both sides

3x + 4 - 2x + 1 = 2x - 1 - 2x - 1

x + 5 = - 2 ( subtract 5 from both sides )

x = - 7

Identify the properties<br><br> 5+(2+7)=(5+2) +7<br> ^2 + ( + ) = ^2+ ( + )<br> h+0=h
TiliK225 [7]
1) 5 + ( 2 + 7) = (5 + 2) + 7

It is the associative property of the addition.

This property states that when adding 3 numbers, the grouping or association of the numbers does not change the result.

2) <span>The second expression is unreabable
</span>

<span>3) h + 0 = h
</span>

<span>It is the identity property.
</span>

This property states that 0 is the identity element of the addition and any number added to  it is equal to the same number.

AS  you know, 5 + 0 = 5, 1234 + 0 = 1234; 0 + 2548 = 2548.
