HELP PLEASE<br> someone its importent
elena-s [515]

Answer:

Step-by-step explanation:

<u>Expression on the board :</u>

12.2x + 50.6 y + 3(1.4x - 2.6y)\\\\= 12.2x + 50.6y + 4.2x - 7.8y\\\\= 16.4x + 42.8y

<u>Expression by the student </u>:

<em><u> Expression 1 </u></em>:

4 ( 4.1x + 10.7 y ) \\\\=  ( 4 \times 4.1x ) + ( 4 \times 10.7 y)\\\\= 16.4x + 42.8y\\\\

The expression 1 is equivalent to the expression on the board. Because the coefficients of x and y are same on both.

<em><u>Expression 2 :</u></em>

<em><u /></em>2 ( 6.1x + 25.3 y + 2.1x -3.9y)\\\\= 2 ( 8.2x + 21.4y)\\\\=( 2 \times 8.2x ) + (2 \times 21.4y)\\\\= 16.4x + 42.8y<em><u /></em>

The expression 2 is also equivalent to the expression on the board. Because the coefficients of x and y are the same.
