hope im right im not sure if it is the same quiz(:

Answer 2

Answer:

Step-by-step explanation:

The Expression

P = 7 x + 4

Q = 3 x + 5 + 4 x -1

Adding like terms , i.e term containing variables and term containing constants

Q = 3 x + 4 x + 5 -1 [You must be thinking why i have written this, keep in mind Commutative law of addition which is , a + b = b  + a, i.e in this expression , 5 + 4 x = 4 x + 5]

So, Q = 7 x + 4

As you can see both P and Q are identical Expressions.

Now we will check each and every option.

1. When x= 2,

P =Q= 7 × 2 + 4= 14 + 4= 18→→→→(True)

2. As for x=4,6

P = Q = 7 × 4 +4=28 + 4=32

P = Q= 7× 6 +4 = 42 +4=46

As , explained above, We saw that both the expressions P and Q are identical.

So , There are infinite values of x , for which these Expression P and Q are identical.
