What is the value of x in the solution to the following system of linear equations?

The correct answer is second answer x = -2

Step-by-step explanation:

It is given that,

y = x - 1 and

y = 2x + 1

To find the value of x

Let, y = x - 1  ---(1)

y = 2x + 1  (2)

From (1) and (2) we can write

x - 1 = 2x + 1

2x - x = -1 - 1

x = -2

Therefore the value of x = -2

The correct answer is second option

$5.41

step-by-step explanation:

$20 - $14.51 = $5.49.
