-4(3-5)+10-3(7+4)+30 ​= -4(-2)+10-3(11)+30

-4(-2)+10-3(11)+30 = 8+10-33+30

8+10-33+30 = 18-33+30

18-33+30 = -15+30

-15+30 = 15

Which expression is not equivalent to the other three?
AVprozaik [17]

Answer:

<em>4 + 7x – 2</em>

Step-by-step explanation:

<u>Equivalent Expressions</u>

Let's find out which expressions are equivalent by simplifying them. One of the expressions should be not equivalent to the other three.

Simplifying

2x + 2+ 2x + 3x -8=7x-6

Now for the second expression

4 + 7x -2=7x+2

The third expression simplifies to

-2 + 5x + 2x - 4=7x-6

Finally, this is the simplification for the expression

8x - x - 6=7x-6

As seen, the only expression not equivalent to the other three is 4 + 7x – 2
