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.

umka2103 [35]

Answer:

Step-by-step explanation:

Given that :

Total Number of scorings (both Teams) = 18

Let :

x = number of 5 point score ; y = number of 2 point score

Total points scored = 34 + 29 = 63

x + y = 18 - - - (1)

5x + 2y = 63 - - (2)

From (1)

y = 18 - x

In (2) ; we have ;

5x + 2(18 - x) = 63

5x + 36 - 2x = 63

3x + 36 = 63

3x = 63 - 36

3x = 27

x = 9

9 5-point plays
