Which linear equations have an infinite number of solutions? check all that apply.

(x – ) = (x – )

8(x + 2) = 5x – 14

12.3x – 18 = 3(–6 + 4.1x)

(6x + 10) = 7(x – 2)

4.2x – 3.5 = 2.1 (5x + 8)

we know that

In a linear equation if the left side is equal to the right side

then

the system has an infinite number of solutions

we're going to verify every case

case A)

In this case the left side is equal to the right side

therefore

the system case A) has an infinite number of solutions

case B)

In this case the left side is not equal to the right side  

therefore

the system case B) does not have an infinite number of solutions

case C)

In this case the left side is equal to the right side  

therefore

the system case C) has an infinite number of solutions

case D)

In this case the left side is not equal to the right side  

therefore

the system case D) does not have an infinite number of solutions

case E)

In this case the left side is not equal to the right side  

therefore

the system case E) does not have an infinite number of solutions

therefore

the answer is

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
