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

h

step-by-step explanation:

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
