Mr. Lindsay wrote the four expressions below on the board
Expression 1: 9 + 5× -- 5 + 3×
Expression 2: 10× + 3
Expression 3: × + 12
Expression 4: 4(1 + 2×)

The two equivalent expressions are 1 and 4
Let's substitute 2 for x

Expression 1
9 + 5(2) - 5 + 3(2) =
9 + 10 - 5 + 6 = 20
Expression 4
4(1 + 2(2)) =
4(1 + 4) =
4(5) = 20

When you substitute 2 for x in expression 1 and 4 you get the same answer of 20.

Expression 1: 9 + 5x - 5 + 3x  and Expression 4: 4(1 + 2x) are equivalent to each other that is 8x + 4.

What is an equivalent?

The equivalent is the expressions that are in different forms but are equal to the same value.

Mr. Lindsay wrote the four expressions below on the board.

Expression 1: 9 + 5x - 5 + 3x

Expression 2: 10x + 3

Expression 3: x + 12

Expression 4: 4(1 + 2x)

On simplifying, the expressions will be

Expression 1: 4 + 8x

Expression 2: 10x + 3

Expression 3: x + 12

Expression 4: 4 + 8x

Then it is clear that the expression 1 and expression 4 are equivalent to each other.
