Which are equivalent expressions?

Check all that are true.

8x - 4y = 4 (-y + 2x)

8x + 4y = 4 (2x + y)

4x - 8y = 4 (-x + 2y)

4x + 8y = 4 (x + 2y)

4x + 8y = 4 (8xy)

Equivalent Expressions are expression that have the same value on both side of the equal sign.

Expression 1:

First simplify both sides of the expression. One of them are already fully simplified.

8x-4y=4 (-y+2x)

8x - 4y=-4y+8x

This expression IS an equivalent expression.

Expression 2:

Do the same as in expression one (we will be simplifying all of the expressions).

8x+4y=4 (2x+y)

8x+4y=8x+4y

This expression IS an equivalent expression.

Expression 3:

4x-8y=4 (-x+2y)

4x-8y=-4x+8y

This expression IS NOT an equivalent expression.

Expression 4:

4x+8y=4 (x+2y)

4x+8y=4x+8y

This expression IS an equivalent expression.

Expression 5:

4x+8y=4 (8xy)

4x+8y=32xy

This expression IS NOT an equivalent expression.
