Equivalent Expressions

How can you identify equivalent algebraic expressions?

Multiple Choice

Use the Distributive Property to write an equivalent expression:

2\left(4x+3\right)

8x + 3

6x + 3

8x + 6

6x + 6

1. Multiply the outside with the 1st number.

2. Multiply the outside with the 2nd number.

3. Put the two together and add the operation from the parenthesis.

$2\left(4x+3\right)=8x+6$
These are known as equivalent expressions.

They have the same value.
You can check if they are equal by substituting X with a number.

Multiple Choice

Which expression is equivalent to:

2x+6

$2\left(x+3\right)$

$x+1+x+2$

$2x+6$
Substitute X in each expression to check the value. (Make x = 2)
$2x+6=2\cdot2+6=4+6=10$

$2\left(x+3\right)=2\left(2+3\right)=2\left(5\right)=10$ -- YES! This is equivalent!
$x+1+x+2=2+1+2+2=7$ -- NO! This is not equivalent.

Multiple Choice

Which expression is equivalent to:

2\left(x+2\right)

2x + 2

2x + 4

$2\left(x+2\right)=2\left(2+2\right)=2\left(4\right)=8$

Substitute X for 2 and compare values:

$2x+2=2\cdot2+2=4+2=6$ -- No! This is not equal to 8.
$2x+4=2\cdot2+4=4+4=8$ -- Yes! This is equal to 8!

Let's Compare Another Way!

Simplify each expression by combining like terms.
Compare the simplified expressions.

Multiple Select

Choose all expressions that are equal to:

5\left(2x+3\right)

$10x+15$

$5x+15+5x$

$10x+8$

Multiple Select

Choose all expressions that are equal to:

4x-8

$2\left(2x-6\right)$

$2\left(2x-4\right)$

$x-8+3x$

Multiple Select

Choose all expressions that are equal to:

12x-16

$9x-16+3x$

$3\left(3x-5\right)$

$4\left(3x-4\right)$
